A gain-clamped two-stage L-band EDFA is demonstrated by simply incorporating two di erent FBGs on both side of EDF in the second stage. It forms a FBG laser at 1560 nm to clamp the gain in the system. The gain is clamped at about 16:5 dB with gain variation of less than 1:0 dB at dynamic range up to

A gain clamping technique for the long wavelength band erbium-doped รฟber ampliรฟer (L-band EDFA) is presented. It uses two circulators and a broad band รฟber Bragg grating to route wasted backward C-band ASE from the second stage and launch it back into the input end of the รฟrst stage of a two-stage a

## Abstract A gain clamping technique for the longโ€wavelengthโ€band erbiumโ€doped fiber amplifier (Lโ€band EDFA) is presented. It uses two circulators and a fiber Bragg grating (FBG) to route a backward amplified spontaneous emission (ASE) from a secondโ€stage amplifier and launch it back into the firs
