Foton’s technical Platforms • CARACAS: Characterizations and assembling technologies for optoelectronics • CCLO: Design, creating, characterizations of photonics components: Optical fibers, Integrated circuits based in polymers, porous silicon and silica, chalcogenide. Coupling and assembling technologies for components. • PERSYST: Characterizations of components and devices for high bit rate telecom systems. Streams from 10 to 160 Gbit/s, 40 channels WDM on Mega-metric lengths. • NANO-RENNES: Design, fabrication and characterizations of epitaxied materials and of photonic components based on nano-structured semiconductor III-V materials for Silicon photonics.

6. PERSYST platform (1) Platform for tEst and Research on optical telecommunications SYSTems (2004) Public structure offering test-bed facilities for the characterization of components for optical communications. Its expertise : Optical transmission systems 10 Gbit/s : optical access network (transmitter/receiver) 40 Gbit/s : WDM recirculation loop (40 channels, 100 GHz spacing); Modulation formats (NRZ, RZ, CSRZ, DPSK, DQPSK(56 Gbit/s)) 160 Gbit/s : Advanced optical functions, recirculation loop Characterisation of photonic and opto-electronic components in system environment Chip characterisations (static and dynamic) High speed electronic interfaces up to 112 Gbit/s (receivers, transeivers based on FPGA, electronics functions for TDM, etc) Bring electronics capability close to optics 01/01/2020

7. PERSYST (2) A well established procedure with the help of juridic services of UR1 (NDA, test quotation, contract). Open to industrial users (Orange Labs, Ekinops, Metconnex): Development of 10 Gb/s BURST receiver Recirculating loop test-bed setting Electrical driver development for fast tunable laser 40 Gb/s system characterisation of a reconfigurable optical add dropp multiplexer (WDM loop experiment) etc With academics : involved in about 15 national and European programs since 2008 : Photonics crystals based optical signal processing Optical sources for access network Carbon nano-tubes for telecommunications applications High capacity transmission and regeneration Etc KM3NeT meeting

8. Our role in Meust Recently contacted by CPPM for system validations: Lab experiments (march 2013): Minimum 2  - 50 GHz spacing - in the C-band Equivalent loss and chromatic dispersion of worst case Continuous data stream at 1 or 10 Gbit/s of Pseudo Random Bit Sequence (231-1 bits) - Non Return to Zero data Use of the REAM of the project (provided by CPPM): condition of use must be defined (Vpp – rising and falling time etc) Based on the architecture of the final system (need information on place and type of amplification, receiver information etc.) Bit Error Rate, eye diagram analysis Final system validation assistance : at CPPM with 80  and the full system (true transmitter, receiver) (summer 2013) Study of the possibility to use ‘Antares’ cable for nodes 4 to 6 (summer 2013) KM3NeT meeting
