A simple gain‐flattened L ‐band erbium‐doped fiber amplifier (EDFA) is demonstrated. An L ‐band flat gain range of 20 nm (1560–1580 nm) is achieved for use in wavelength‐division multiplexing (WDM) transmission systems. Gain flatness with a 1 dB gain discrepancy is obtained through manipulation of the pump power, and no additional devices (gain equalizer, attenuator, fiber‐Bragg grating) are required. © 2000 John Wiley & Sons, Inc.
