Paper Abstract

We have developed and prototyped C+L band erbium-doped fiber ASE source by making use of both forward and backward ASEs with double-pass configuration. Simulations and experiments are performed for different pump powers and fiber lengths to optimize the design. The spectrum bandwidth of 80.6nm (1526.7~1607.3nm) with flatness of 5.22dB is realized. Pumping-conversion efficiency of about 18.9% is reached. This C+L band light source will be used to extend illuminating bandwidth of the high-speed interrogator which has been prototyped and been used by different clients. The sampling rate can be up to 5 kHz. The broadband light source allows the interrogator no moving part that enables high-speed FBG sensor interrogation.
