POLYSYS aimed to realize for the first time serial 100 Gb/s direct connectivity in rack-to-rack and chip-to-chip data communications systems. In specific, POLYSYS focused on the development of photonic and electronic components operating directly at 100 Gb/s based on electro-optic polymers enabling the best possible material compatibility with current polymer-based optical backplanes. The technical objectives of POLYSYS were achieved through the cost-effective polymer material system for realizing the electro-optic components and the utilization of InP for developing high-performance optical and optoelectronic components. After 40 months of development efforts it can be said that POLYSYS has been extremely successful in helping EO polymers evolve from a device specific technology into a broader purpose platform for small-scale and high-performance integrated circuits for datacom applications. Achievements to this direction include: The monolithic integration of MMI couplers and tunable Bragg-gratings together with MZMs on EO polymer chips. The hybrid integration of InP chips (laser diodes, gain chips, photodiodes) with EO polymer chips and the development of lasers with 17 nm tunability combining InP gain chips with monolithic Bragg-gratings. The integration of EO polymer chips with InP-DHBT circuits using wire-bonds and the packaging of integrated transmitter modules. At the same time, POLYSYS has also been extremely successful in extending the limits of InP photodetector technology and developing quad arrays of pin-photodiodes and pinTWAs with potential for 100G operation, as well as in advancing the state-of-the-art of InP-DHBT technology and developing novel MUX-DRV circuits and twin-DEMUX circuits for operation at 100 Gb/s. Through the integration of all these components, POLYSYS has impressively achieved the final packaging of six out of the seven modules that had targeted: The 100 Gb/s transmitter The 2x100 Gb/s transmitter The tunable 100 Gb/s transmitter The 100 Gb/s integrated optical interconnect The 4x100 Gb/s pin-DEMUX receiver The 4x100 Gb/s pinTWA-DEMUX receiver Four of these modules (100G Tx, 2x100G Tx, tunable 100G Tx and 4x100G pin-DEMUX receiver) were successfully tested and confirmed the potential for error-free operation at 80 and 100 Gb/s and transmission over SMF links of at least 1km without dispersion compensation, whereas the testing of a fifth one (4x100G pinTWA-DEMUX) will be completed after the final review meeting. POLYSYS gained remarkable visibility through a variety of dissemination actions and prestigious publications (including the ECOC 2012 PDP), and succeeded in defining concrete exploitation plans by all partners. Significant achievements that are related to the actual exploitation of the foreground knowledge are the industrial strategic partnership between GigOptix and HHI in the last period of the project and the funding of a follow-up research project (http://www.ict-panther.eu/) that was based on the knowhow of POLYSYS.
PhoxTroT is a large-scale research effort focusing on high-performance, low-energy and cost and small-size optical interconnects across the different hierarchy levels in data center and high-performance computing systems: on-board, board-to-board and rack-to-rack. PhoxTroT will tackle optical interconnects in a holistic way, synergizing the different fabrication platforms in order to deploy the optimal “mix&match” technology and tailor this to each interconnect layer.
PCRL is coordinating BIOFOS. Current methodologies for detection of food contamination based on heavy analytical tools cannot guarantee a safe and stable food supply. The reasons are the complexity, the long time-to-result (2-3 days) and the cost of these tools, which limit the number of samples that can be practically analyzed at food processing and storage sites.
PCRL coordinates SPIRIT. Bandwidth‐hungry end‐user applications are stretching physical layer capacity and dictating the migration towards software-defined flexible architectures. Fully-programmable optical components supporting rate- and format-adaptation are urgently needed.
PCRL coordinates PANTHER. Multi-rate, multi-format and multi-reach operation of optical transceivers is important, but it is not enough for next generation terabit products. What is still missing to make these products viable is a solution for the flexible control of this enormous capacity at the optical layer and its distribution among a number of independent optical flows. PANTHER aims to provide this solution and develop multi-rate, multi-format, multi-reach and multi-flow terabit transceivers for edge switches and data-center gateways.
PCRL participates in the ORCHESTRA project which aims to develop a highly-flexible optical network that can be dynamically reconfigured and optimized. It does this by constantly monitoring impairment information provided by the network’s coherent transceivers that are extended, almost for free, to operate as software defined multi-impairment optical performance monitors (soft-OPM).
