IRIS project(Integrated Reconfigurable silicon photonics based optical Switch)

Lessons learned from experience

History teachs …

• Our story began in 2011. The first proposal was SIRIO

• Evaluation result: Not funded

• … so our story begins with a failure !!!

WHY ?

2

SIRIO Evaluation part 1

SIRIO Evaluation part 2

SIRIO Evaluation part 3

Our Mistake was…

• Our mistake was to under-estimate the project management …

• Which is the most “standard” area,

• and also the most “discretional” area….

Lessons learned…• The first lesson learned was:

take care of the project management

• The second lesson was:

… if at first you don’t succeed, try, try try again…

So we set up a new proposal “IRIS” in 2012 and the evaluation results were…

IRIS Evaluation part 1-2

IRIS Evaluation part 3

Lessons learned !! …• IRIS was approved at the end of 2013 (2014-2016)

• During the last year, the third year of the project, we got an extension of 12 months until the end of 2017

• This is not so common…

With an interesting follow up…

• In 2014 we set up other 3 projects

• Teraboard

• Cosmicc

• Streams

…..All funded in 2015…!!!

Using a new technology: Si Photonics

Power needed/Ring :21 nm / (3 nm/10 mW) = 70 mW

A possible implementation of the switch element

Ring resonator with Ti/TiN heater above, and resonance peak wavelength temperature dependence

European leadership: IRIS is beyond the State of the Art

Exploitation: the Roadmap of HW

Do what you promised5.7 m

m

2.9 mm

1390 Optical Functions per chip

~ 150 O.F./mmq

IRIS target was 1100Optical Functions per chip

The prototype has 1390Optical Functions per chip

But we did more: our integration in terms of O.F./mmq is the best reported today

It is:~ 150 O.F./mmq in the ring area and 85 O.F./mmq in the core area showed

Conclusion: my suggestions

• Find the real frontiers/barriers of a field and choose one or more of them

• Propose one/more breakthrough solutions

• Explain clearly how to implement it/them and how to bypass the associated risks

• Find one good partner per every activity requested by the project

• Pay attention to the project management

• Describe the impact on your business and your exploitation
