Gain clamped L-band EDFA using a fiber Bragg grating in two stage configuration
A gain clamping technique for the long-wavelength-band erbium-doped fiber amplifier (L-band EDFA) is presented. If uses two circulators and a fiber Bragg grating (FBG) to route a backward amplified spontaneous emission (ASE) from a second-stage amplifier and launch it back into the first stage. The...
