The gain improvement in two-stage long wavelength band erbium doped fiber amplifier (L-band EDFA) is demonstrated by incorporation of broadband C-band fiber Bragg grating (FBG). The FBG is used to reflect the unwanted backward C-band ASE from second stage back into the system. The proposed technique...
