A gain-clamping technique in two-stage double-pass L-band EDFA is demonstrated using a single fiber Bragg grating (FBG). Two types of FBGs, broadband and narrowband, have been used in the gain-clamped system. The gain is clamped at 18.7 and 17.5 dB for the design with narrowband and broadband FBGs,...
