Large Optical Bandwidth by amplifier Systems based on TEllurite fibres doped with Rare earths

Objective

An ultra-broadband optical amplifier prototype based on tellurite fibres doped with rare earths ions will be entirely fabricated by the consortium. By combining two amplifiers, whose main dopants will be Erbium and Thulium, a usable amplified optical bandwidth of more than 140 nm in the range 1.45-1.62 µm will be covered. Such a large bandwidth is not achievable with today's technology entirely based on doped silica fibre. Different pumping configurations will be tested to get an optimised (in terms of gn and noise figure) and compact device. Taking into account the present trend towards DWDM systems, an integration of tellurite amplifiers into existing networks could enhance their capacities significantly. By using an optical transport network (OTN) ts-bed composed of Optical Add-Drop Multiplexers (OADM) and Optical cross-Connects (OXC), the consortium will demonstrate the possibility of full compatibility with typical optical networking functions
