Abstract

Gain enhancement in a long‐wavelength band (L‐band) erbium‐doped fiber amplifier (EDFA) is demonstrated using a broadband fiber Bragg grating (BB FBG) that reflects the L‐band amplified spontaneous emission (ASE) and L‐band signal back into the system. The reflected L‐band signal is then pumped by the unused conventional band (C‐band) backward ASE, resulting in gain improvement. Gain enhancement as high as 11 dB is obtained for a 1560 nm signal, with an input power of −30 dBm at 98 mW of pump power. The noise figure for the wavelength is measured to be 4 dB. © 2002 John Wiley & Sons, Inc. Microwave Opt Technol Lett 32: 388–390, 2002.

## Abstract A gain clamping technique for the long‐wavelength‐band erbium‐doped fiber amplifier (L‐band EDFA) is presented. It 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 firs
