Photonics research programmes to revolutionise healthcare technologyLight is used in a multitude of ways to identify molecules, detect disease and manipulate chemical and cellular processes. Novel low-cost light sources, advanced detection schemes, new materials and nanotechnologies are now enabling further rapid growth in the application of light to chemistry and medicine. Here we describe new ORC directions in devices and techniques for DNA analysis, point-of-care diagnostic systems, mid-infrared and pulsed light sources and integrated photonic devices which will advance our understanding of biochemical processes and generate advanced optical healthcare technologies.

“Photonic technologies are set to revolutionise our access to chemical and biochemical information, driven by the demand for fast, low-cost, automated chemical analysis in a multiplicity of applications from food safety, water quality, security and rapid point-of-care diagnostics.” Professor James Wilkinson

New DNA sequencing research awarded BBSRC funding A new method of single molecule DNA sequencing is being developed by scientists at the University of Southampton with funding from the Biotechnology and Biological Sciences Research Council’s Strategic Tools and Resources Development Fund.

The aim of the research is to create novel devices for the direct optical interrogation of single DNA strands.

The human genome contains 3164.7 million nucleic acid bases (adenine, guanine, cytosine, thymine). The DNA sequence provides information about ancestry, hereditary disease, features (such as eye, skin or hair colour) and physiological ‘make-up’.

Dr Tracy Melvin from the University of Southampton’s ORC explains: “In order to improve our understanding of genome sequences it is desirable to have simpler DNA sequencing methods. By optically ‘reading’ DNA directly, we hope to eliminate the complex biochemical processes currently used so that genomes can be sequenced much faster and more cheaply.”

Using the new state-of-the-art fabrication facilities in the University’s Mountbatten building, the multidisciplinary team from the ORC and Chemistry will fabricate nanoscale structures which will be used optically to

‘read’ the single DNA strand sequence.

This study will provide the first step for a new single molecule DNA sequencing method that builds upon existing expertise at the University of Southampton and will involve collaboration with Renishaw Diagnostics, which is providing material and expertise.

ORC Professor awarded major funding for biophotonics programmeProfessor James Wilkinson at the Optoelectronics Research Centre has been awarded a European Research Council (ERC) Advanced Grant to realise tools for fast, low-cost point-of-care clinical diagnostics and for chemical analysis in water pollution and food safety.

The £2.6 million grant will advance the frontiers of biophotonics research in near- to mid-infra-red devices. Commencing early this year, the five-year programme aims to develop mass-manufacturable integrated photonics technology for chemical and biochemical analysis and advanced spectroscopic techniques for biomedical diagnostics.

“Photonic technologies are set to revolutionise our access to chemical and biochemical information, driven by the demand for fast, low-cost, automated chemical analysis in a multiplicity of applications from food safety, water quality, security and rapid point-of-care diagnostics,” said Professor Wilkinson.

“The micro-manufacturing approaches that have led to the ubiquitous presence of the mobile phone and digital camera are expected to lead to a similar widespread deployment of chemical and bioanalytical microsystems.”

ERC Advanced Grants fund cutting-edge research by the very best established research leaders in Europe. The European Research Council intends that projects funded by these competitive and selective grants be highly ambitious, pioneering, and creative in their approach. The grants support research that takes risks, employing unconventional methodologies and investigations between established disciplines, and presenting the possibility of a major breakthrough with far-reaching impact.

This year’s call drew nearly 2,300 project proposals from across the spectrum of research fields. Typically approximately 14 per cent are funded, with last year’s call funding researchers of 26 nationalities working in 18 EU countries.

New BBSRC funding award for epigenetic analysis applicationsDr Tracy Melvin at the Optoelectronics Research Centre and Professor Tom Brown of Chemistry at the University of Southampton in collaboration with Professor Jeremy Baumberg of the Nanophotonics Centre, University of Cambridge have been awarded £1 million by the BBSRC to create new biophotonics and DNA technology for epigenetic analysis applications.

Epigenetics is a term first introduced by Waddington in 1942 and this was used to describe “the interaction of genes with their environment, which bring the phenotype into being”. Today the genomes of many organisms (humans, plants, invertebrates and vertebrates) have been sequenced and many of the genes identified – but knowing the genomic DNA sequence does not allow us to predict the life, health and death of these organisms. In order to understand how the environment affects the destiny of these organisms, we need to learn how the surroundings as well as the DNA sequence play a role.

Although DNA is composed of four nucleic acid bases, adenine, guanine, cytosine and thymine, there is a ‘fifth’ nucleic acid base, methyl cytosine. The methylation of cytosine occurs as a result of an enzymatic process which is triggered by cues (including for instance, diet, lifestyle).

The Southampton and Cambridge teams will develop new technologies for the detection of methylcytosine and unmethylated cytosine within sequences of single DNA molecules. Within the 42 month programme the teams plan to demonstrate the technology for developmental biology questions with Professor Wolf Reik at Babraham Institute, Cambridge, and plant biology questions with Professor Teresa Roldan-Arjona at Cordoba University, Spain.

Grants for new devices for healthcare and industryNew applications in healthcare and telecommunications will be made possible by two grants awarded to the Optoelectronics Research Centre (ORC) by the Engineering and Physical Sciences Research Council (EPSRC).

A grant for £0.5 million awarded to a team led by Dr Anna Peacock, will combine two important and highly topical optical technologies: optical fibre tapers and semiconductor functionalised fibres. This research will lead to the development of optoelectronic devices spanning a wide range of wavelengths with the potential to impact many disciplines.

“The award of this grant is very exciting as this research will be crucial for the development of our semiconductor fibre technology and its potential applications,” said Dr Peacock. “The construction of commercially relevant devices such as ultra-compact broadband, mid-infrared sources for healthcare, frequency comb generators for spectroscopy and sensing, and highly nonlinear optical couplers and switches for ultrafast telecoms applications should stimulate a fruitful collaboration with industry.”

New advances in ultrafast fibre laser technology at the ORC and a grant for £0.6 million will also make it possible to demonstrate table-top mid-infrared lasers with sufficient power to efficiently ablate and deposit high-quality thin polymer films for numerous applications.

“In this grant we aim to demonstrate the highest power and highest pulse energies yet reported from an ultrafast Optical Parametric Oscillator (OPO),” said Professor David Shepherd. “This power scaling is made possible by new advances in ultrafast fibre laser technology at the ORC, which will act as the pump source for these OPOs. This then takes OPOs, which have previously been seen as primarily scientific tools for laser laboratories, into a regime where they could be useful for materials processing and consequently a number of real-world applications covering photonics, electronics and medicine.”

New grant for photonic technologiesA grant awarded to the ORC will provide a platform for the development of the next generation of cheaper, faster and greener devices.

The ORC has just been awarded a £1.4 million platform grant by the Engineering and Physical Sciences Research Council (EPSRC) in the area of integrated photonics which will lead to the development of new devices including new kW-class lasers, compact on-chip amplifiers and biosensor arrays for infectious diseases.

High-power lasers, the size of a fingernail for machining and laser-processing applications, pollution sensors to monitor climate change, early threat detection security devices and fast universally accessible disease screening, will all be made possible throughout the four-year period of the grant.

The investigating team are Professor Rob Eason, Principal Investigator, with co-investigators Professors James Wilkinson, Dave Shepherd, Peter Smith and Dr Jacob Mackenzie, who are working with seven external partner organisations and each responsible for specific areas of interest.

“We have been working in integrated photonics for 20 years and we will now use this technology to focus on healthcare, sensing and telecommunications,” said Professor Eason

The grant will make it possible for the ORC to carry out feasibility studies for industry and provide a rapid response.

“Platform funding will enable a rapid response to the needs of industry,” said Professor Eason. “It will make it possible for a targeted end application to be designed, developed and demonstrated in a matter of weeks to months, compared to the more usual months to years under current funding. Industry often needs ‘instant’ solutions to problems and this grant should go a long way to meeting this need.”

During the course of the grant, the investigators will develop new technologies which they will then test with the industrial partner organisations.

The seven companies involved in the project are:– Covesion Ltd– Stratophase Ltd– Gooch and Housego– Element Six Limited– Ocean Optics– US Air Force– Defence Science and Technology Lab

Celebrating the achievements of ORC students

Student success

The Institute of Physics (IOP) has awarded ORC graduate, Dr Eric Plum, their Quantum Electronics and Photonics PhD Thesis Prize for his Thesis entitled “Chirality and metamaterials.”

This is the second year running that the £250 prize has been awarded to an ORC graduate, after it was awarded to Dr Nikitas Papasimakis last year.

Prior to receiving this prize Eric’s thesis had been widely publicised through 47 publications including three Physical Review Letters, a book chapter and 18 conference papers linked to invited and keynote talks.

The prize recognises Eric’s theoretical description and experimental realisation of novel metamaterials with optical activity, asymmetric transmission and negative refractive index, which have already attracted hundreds of citations.

On receiving the prize Eric commented “I am honoured to receive the thesis award from the Institute of Physics and I would like to take the opportunity to thank Professor Nikolay Zheludev and Dr Vassili Fedotov for their guidance during my PhD.”Eric has recently been appointed as a Leverhulme Advanced Research Fellow associated with the EPSRC Centre for Photonic Metamaterials.

This year’s graduation ceremony was a VIP affair with former University of Southampton Vice-Chancellor, Professor Sir William Wakeham being honoured along with 8 graduands and 2 research fellows from the ORC.

The reception was hosted by ORC Director, Professor David Payne, at the ORC where graduands and guests enjoyed fresh strawberries and sparkling wine before attending the Physical and Applied Sciences’ ceremony in the Turner Sims Concert Hall presided by Sir John Parker.

Principal Research Fellow, Dr Sakellaris Mailis was presented with a 2011 Post Graduate Research Supervision Award in recognition of his excellence in the supervision of research students while Senior Research Fellow, Dr Peter Horak, in recognition of his innovation and high quality dedication in the field of learning and teaching, was presented with a 2011 Vice-Chancellor’s Award in Inter-professional Learning and Teaching.

Celebrating the achievements of ORC students

PhD student Joseph Kakande, from Uganda, was selected as one of only three Marconi Young Scholars in this fourth year of the awards for his cutting-edge work in making communications even faster by using all-optical fibres. Marconi Society Chairman Emeritus Robert Lucky said that the scholars selection committee “looked for candidates who showed the potential to win the Marconi Prize – the equivalent of the Nobel Prize in communications science – at some point in the future. As a point of reference, Marconi Fellows have been at the forefront of every modern advance in telecommunications and the Internet.”

Joseph’s work focused on all-optical signal processing as the means of meeting the growth in demand for high-capacity optical communications. The current system of optical-to-electrical-to-optical conversion creates speed and power bottlenecks that cannot sustain the exponential growth in communications. “Electronics is really great for processing,” Joseph explains, “but it can only work so fast.”

Newer technology aims to replicate the functionality of electronic transistors, but uses optical components – flexible pure glass fibres roughly the size of a human hair that are capable of transferring information from one end to the other over longer distances. The advantage is speed: optical techniques easily process more than 10 billion bits a second – about 10 times faster than the fastest conventional computer.

Joseph’s research aims to develop novel methods for processing high spectral efficiency phase-encoded optical signals at ultra-high baud rates, using nonlinear fibre optic technologies. In essence, that means using light to control optical signals on ultra-fast time scales. His research is already published in several top journals including the Nature group, and has led to three patent filings, with more in the pipeline.

ORC student wins Marconi Young Scholar awardA talented engineering researcher from the Optoelectronics Research Centre, has been honoured at the prestigious Marconi Society Awards in San Diego, California.

Joseph is congratulated by Robert Tach at the Marconi Society Awards

Joseph would like to work for a large corporation in its research and development department. He says: “As a child, I had a fascination with electronics and I always wanted to work at Intel.”

Named Best Student at National Level in Uganda, where he was a student at St Mary’s College Kisubi, Joseph attained first-class honours in electronic engineering from the University of Hull, and is shortly to receive his PhD in optoelectronic engineering from the University of Southampton. His particular interest is in exploring how optical communications, which have revolutionised technology in the developed world, can be deployed in the Third World to empower its most deprived people. As his University co-supervisor, Optoelectronics Research Centre Deputy Director David Richardson says, “I think Joseph has all the capabilities to become a real research superstar.”

Page 12: Light Times

The award recognises student leaders in the field of optical communications: finalists are judged on innovation, research excellence and presentation skills.

Selected from 362 submissions, Eric’s paper relates his research on Spatial Division Multiplexing (SDM) in hollow-core photonic bandgap fibres. He explains:

“In recent years, SDM has emerged as one potential solution to the predicted capacity crunch in current telecom systems. By implementing SDM in hollow-core photonic bandgap fibres, we exploit the benefits of low optical nonlinearity and potential low loss that result from light propagation in a hollow-core. One of the first steps is to fully understand the properties of these fibres and in particular the mechanisms responsible for loss. At the conference, we presented a method that accurately describes light scattering at the many air-glass surfaces within the fibre.

“The Corning student paper competition at the OFC is a big deal for students working in Optical Communications and it was simply amazing to win. I am grateful to my supervisors Dr Francesco Poletti and Professor David Richardson for their support and guidance, as well as our marvellous fabrication team.”

ORC students are making the grade at CLEO this year: they’ve had a 100 per cent success rate for their submissions to one of the Photonics Industry’s premier events. All 36 of the papers submitted have been accepted for presentation.

Professor Michalis Zervas said: “This is a great achievement given that this year there were 176 submissions to Category 11 alone (the highest number among all the categories) and the success rate was about 40 per cent. It was a really tough competition.”

Congratulations to you all, especially Ee Leong Lim, whose paper got the highest score among the ORC submissions.

CLEO: Science & Innovations is the “classic” CLEO which for over 35 years has reported applied research results on all types of lasers, optical materials, and photonic devices. Topics include laser processing of materials, terahertz technologies, high-field and ultrafast optics, optical communications, biophotonics, optical sensing and metrology, micro- and nano-photonics and non-linear optics.

Bridging the gap between glass and siliconThe University of Southampton’s Optoelectronics Research Centre (ORC), in collaboration with the Universities of Surrey and Cambridge, is pioneering research that will develop functionality of new materials such as amorphous chalcogenides.

Light Times | issue 1 2012

Page 15: Light Times

These materials bridge the gap between glasses, such as those that form our optical fibre networks, and semiconductors, such as the silicon chip. Chalcogenides are already in use for thin-film and fibre waveguides, switching, light emission and amplification while electronic applications, such as phase-change memory, are leading the way in microelectronics.

Microelectronics is a vast market; worldwide production was €873 billion in 2010, with European volume growing 23% that year. The gadget economy is becoming a bigger and bigger part of the business world, and may be one of its more important growth engines. The materials being developed in this project are already forming the basis for a new generation of electronics.

Professor Dan Hewak, project leader from the ORC, says: “We expect this project to generate considerable attention in both research and industrial communities. This research will stimulate interest in further electrical and optical applications of chalcogenides on a local and international scale, particularly as we move towards commercial realisation. Many of the device goals, such as LEDs, photodiodes, photovoltaic cells, optical

amplifiers, switches, logic gates and memory cells will be of great interest to large electronics companies.”

The ORC has long established links with leading international companies including BAE Systems, Qinetiq, Ilika Technologies plc, Gooch & Housego and IBM. Industrial interest is further reinforced by the involvement of a leading international expert in the field of applications of ion implantation, Dr Jonathan England, who is Senior Technologist at Varian Semiconductor Equipment Associates (VSEA), a subsidiary of Applied Materials. Jonathan is undertaking the role of project mentor, with VSEA sponsoring his time to the project.

Dr Richard Curry, University of Surrey project leader, explains: “Our work will impact on policy makers, stakeholders, research councils and government - providing clear measurable results that demonstrate the value of investment in UK-led research. Ultimately, the development of new technologies to assist commerce, healthcare and improved device energy efficiencies will provide long-term benefits to the economy and society as a whole.”

Professor Stephen Elliott, University of Cambridge project leader, adds: “This combined computational and experimental project holds out the promise of delivering new functional materials, with a wide range of applications of interest to industry, and which should provide opto-electronic technologies beyond silicon.”

The £1.48 million Engineering and Physical Sciences Research Council (EPSRC)- funded project forms an important component of the EPSRC’s Grand Challenge in Microelectronics entitled, ‘Performance Driven Design for Next Generation Chip Design’.

The grant is initially awarded over two years during which the number and range of collaborations and industrial interest is expected to grow in the new chalcogenide-based optoelectronic platform.

His Royal Highness, the Duke of York, was presented with the so-called ‘Superman memory crystal’ from Professor David Payne, ORC Director, during his recent tour of the ORC. The nanostructured fused quartz medallion, was imprinted by a femtosecond laser with an image of the Duke. The technology enables vast quantities of five-dimensional data to be stored indefinitely. To accompany the gift, a laser-etched plaque was also presented, courtesy of ORC spin out company, SPI.

“The Duke was fascinated by our start-up record and mused on the merits of inward investment versus organic growth to create the major British companies of the future. He noted the success of SPI in particular, having met them at the careers fair,” said David.

Commenting on the visit, the Duke said: “I came to the university to see what they are doing and to understand the world-class research that is going on here, especially in optoelectronics in which it is a global leader.”

Find out more about nanostructured glass, the technology behind the gift on page 18.

A team of top researchers from the ORC, led by Professor David Payne, visited Kochi in December to participate in the UK-India Education Research Initiative final meeting. David, as well as chairing session one of the conference, gave a pre-dinner speech on the first evening.

“At this event we’ve presented findings from our major collaborative project: ‘Application-Specific Microstructured Optical Fibres’ (MOFs). This fascinating variant of optical fibres, enables easy manipulation of light propagation, opening up new applications in telecommunications and beyond.” commented David.

MOFs offer high nonlinearity or extremely low nonlinearity capabilities: high nonlinearity capability enables the generation of broadband and coherent supercontinuum light for applications in optical coherence tomography (OCT) used in medical diagnosis, or for use as frequency combs. Strongly wavelength sensitive, MOFs offer a new platform for design and realisation of a wealth of all-fibre exotic devices.

“The ORC is proud to be involved in the UKIERI programme, underpinning successful partnering and mentoring relationships between the UK and Indian ministries, institutions and sectoral experts,” David added.

The UKIERI programme started in 2006 with the aim of developing opportunities for UK-India collaboration across academic research, schools and further education colleges. Among the successes of the first five years, UKIERI has:

– invested in 182 UK-India partnerships– supported 55 PhD scholarships and fellowships and

88 facilitation grants– given 393 British students the opportunity to visit and

study in India – facilitated work placements to 106 Indian graduates

The ORC is working on the £2.7 million research project called FLITES (Fibre-Laser Imaging of gas Turbine Exhaust Species). It is funded by the Engineering and Physical Sciences Research Council, led by University of Manchester and aims to develop technology to reduce jet engine emissions.

“FLITES will allow us to map different chemical species and soot in the exhaust plume of aero engines,” said Professor Johan Nilsson at the ORC. “This will create a better understanding of the combustion process in the engine and enable us to optimise it at lower cost - with the increasing interest for substitution of fossil fuels with bio-fuels in the aviation industry, this is particularly important. Currently the cost is too high and the data collected too limited for extensive evaluations of new bio-fuels in aero-engines.”

FLITES aims to establish a world-leading capability to map several exhaust species from aeroplanes using tomographic imaging.

The ORC, the University of Manchester, the University of Strathclyde, and commercial partners including Rolls-Royce, Shell, Covesion, Fianium and OptoSci, will work on the four-year study, motivated by lower-cost engine evaluation and monitoring and reduced carbon dioxide emissions and pollution.

It is expected that the research project will enhance turbine-related research and development capacity in both academia and industry by opening up access to exhaust plume chemistry.

It will underpin a new phase of low-net-carbon development that is underway in aviation, based on bio-derived fuels, and which entails extensive research in turbine engineering, turbine combustion, and fuel product formulation.

Researchers at the Optoelectronics Research Centre have developed new nanostructured glass optical elements, which have applications in optical manipulation and will significantly reduce the cost of medical imaging.

In a paper entitled Radially polarized optical vortex converter created by femtosecond laser nanostructuring of glass, published in Applied Physics Letters, a team led by Professor Peter Kazansky at the University of Southampton’s ORC, describe how they have used nano-structures to develop new monolithic glass space-variant polarization converters.

These millimetre-sized devices generate whirlpools of light that enable precise laser material processing, optical manipulation of atom-sized objects, ultra-high resolution imaging and potentially, table-top particle accelerators.

In a recent breakthrough, the research team found that the technology can be developed further for optical recording; at sufficient intensities, ultra-short laser pulses can be used to imprint tiny dots (like 3D pixels) called voxels in glass. Their previous research showed that lasers with fixed polarization produce voxels consisting of a periodic arrangement of ultra-thin (tens of nanometers) planes. By passing polarized light through such a voxel imprinted in silica glass, the researchers observed that it travels differently depending on

the polarisation orientation of the light. This form birefringence phenomenon is the basis of their new polarisation converter.

The advantage of this approach over existing methods for microscopy is that it is 20 times cheaper and it is compact.

“Before this we had to use a spatial light modulator based on liquid crystal which cost about £20,000” said Professor Peter Kazansky. “Instead we have just put a tiny device into the optical beam and we get the same result.”

Since publication of the paper in 2011, the researchers have developed this technology further and adapted it for a five dimensional optical recording. Traditional CDs and DVDs store data on their surface in two dimensions, and holographic discs can store it in three.

“We have improved the quality and fabrication time and we have developed this five dimensional memory which means that data can be stored on the glass and potentially last forever,” said Martynas Beresna, lead researcher for the project. “No one has ever done this before.”

The researchers are working with the Lithuanian company Altechna to introduce this technology to the market. This work was done in the framework of EU project Femtoprint.

Crystalline materials enable high speed electronic function in optical fibresScientists at the University of Southampton, in collaboration with Penn State University have, for the first time, embedded the high level of performance normally associated with chip-based semiconductors into an optical fibre, creating high speed optoelectronic function.

A gigahertz bandwidth semiconductor photodetector is integrated directly inside a microstructured optical fibre, adjacent to its light guiding core. Finite element analysis in this image shows how this semiconductor device couples seamlessly with data pulses in the glass optical fibre.

The potential applications of such optical fibres include improved telecommunications and other hybrid optical/electronic technologies. This transatlantic team will publish its findings in the journal Nature Photonics.

The team has taken a novel approach to the problems traditionally associated with embedding this technology. Rather than merge a flat chip with a round optical fibre, they found a way to build a new kind of optical fibre with its own integrated electronic component, thereby bypassing the need to integrate fibre-optics onto a chip. To do this, they used high-pressure chemistry techniques to deposit semiconducting materials layer by layer directly into tiny holes in optical fibres.

“The big breakthrough here is that we don’t need the whole chip as part of the finished product. We have managed to build the junction - the active boundary where all the electronic action takes place - right into the fibre,” University of Southampton Principal Research Fellow, Dr Pier Sazio said. “Moreover, while conventional chip fabrication requires multimillion dollar clean room facilities, our process can be performed with simple equipment that costs much less.”

John Badding, Professor of Chemistry at Penn State, explains: “The integration of optical fibres and chips is difficult for many reasons. First, fibres are round and cylindrical, while chips are flat, so simply shaping the connection between the two

is a challenge. Another challenge is the alignment of pieces that are so small. An optical fibre is the width of a human hair. On top of that, there are light-guiding pathways that are built onto chips that are even smaller than the fibres by as much as 1000 times, so imagine just trying to line those two devices up. That feat is a big challenge for today’s technology.”

Dr Anna Peacock, who holds a Royal Academy of Engineering Research Fellowship, added:

“The incorporation of optoelectronic device functionality inside the optical fibre geometry is an important technological advance for future networks. In this sense, we can start to imagine a scenario where the data signal never has to leave the fibre.”

The research also has many potential non-telecommunications applications. It represents a very different approach to fabricating semiconductor junctions that the team is investigating.

Postdoctoral Researcher, Dr Noel Healy concludes: “This demonstration of complex in-fibre optoelectronic engineering is exciting as it has the potential to be a key enabling technology in the drive for faster, lower cost, and more energy efficient telecommunications.”

The research was funded by the Engineering and Physical Sciences Research Council of the United Kingdom and the U.S. National Science Foundation.
