摘要：

A clamped gain of 28 dB is obtained in an L-band erbium-doped fiber amplifier (EDFA) using only 84 mW of a 980 nm total pump power with 100 in EDF. Such highly efficient gain-clamped L-band EDFAs are achieved by simply adding an FBG and optical circulator to create a laser in a cavity for gain clamping. The amplifier gain is clamped at 28 dB for the dynamic range within -20 dBm with a gain variation of less than 0.2 dB. This gain-clamped amplifier also can support a 12-channel wavelength division multiplexing (WDM) system with a gain drop of less than 0.8 dB. The amplifier is expected to be able to support more channels if the laser is set at a wavelength that is within the L-band amplification region.
