iXblue and Photonics Bretagne Deliver Multicore EY Doped Fiber
After a first phase of design optimisation, an optical fibre, including twelve Erbium/Ytterbium co-doped cores, has been fabricated by a partnership of iXblue and Photonics Bretagne. The duo worked together as part of the Evolution des inFrastructures de réseaux de Fibres optiques grâce à L’Amplification à fibres Multi-coeurs (EFFLAM) project.
Based on end-user requirements, the collaborative EFFLAM project has been built to develop power efficient components based on multicore rare-earth doped fibres in order to reduce size and cost of optical amplifiers and Reconfigurable Optical Add and Drop Multiplexers (ROADMs). Partners involved in the project are Lumibird (formerly Keopsys), iXblue, Photonics Bretagne, Orange Labs, Ekinops, Telecom Paris-Tech, and Institute Mines-Telecom/Telecom Bretagne. The three year project, funded by BPI France, Région Bretagne and Lannion Trégor Communauté, started in 2016.
The new active optical fibre has been characterised and delivered to Lumibird,the enterprise in charge of developing fan-in/fan-out technologies that will allow the integration of the advanced fibre into an amplifier prototype. Its evaluation by end-users (Ekinops and Orange), in terms of both optical performances and power consumption, is expected by the project end.
