2020 drivers
• Mobile, data center and cloud applications
• Annual global IP traffic will surpass the zettabyte threshold (1.4 zettabytes) by the end of 2017 [Cisco, Sandvinne]
• Metro traffic will surpass long-haul traffic in 2014, and will account for 58 percent of total IP traffic by 2017
• Surging demand is pushing current static networks to their limits
SPIRIT vision
• Scale transceiver capacity to 1Tb/s
• Single and multi-carrier QAM (up to 16bits/s/Hz spectral efficiency)
• Variable Baud rate (up to 32 Gbaud)
• Introduce flexibility in data transmission
• Shape traffic spectrum based on application requirements
• Gridless operation for Tb/s Superchannels
• Add intelligence in the optical transport
• SDN platform development
• Performance monitoring
• Leverage cost/performance benefits
• power & cost savings by at least 50% Software Defined
Flexible Transceiver
Terabit superchannel
SPIRIT Objectives
• Fabrication of high-speed, low-voltage drive (Vπ ≈ 1V), InP MZM modulators with segmented electrodes
• Fabrication of low-power CMOS PATH modulator logic circuit and binary driver arrays based on cost-efficient 40nm CMOS processing
• Fabrication of an optical MUX/DEMUX based on tunable filters for superchannel grooming on a gridless basis (<10GHz step) over the C-band
• Development and fabrication of packaged and fiber-pigtailed fully-programmable, high-speed, low-power, integrated flexible transceivers on SOI
• Evaluation of fixed-grid and gridless 400G, 1T and flexible (super)channel data transport with advanced DSP and monitoring built-in functions enabled by software control
SPIRIT will blend the best of photonics and electronics technologies on a common integration platform to build high performance, low cost and power efficient flexible, programmable transceivers
