摘要：
An erbium-doped fiber amplifier (EDFA) is simulated. The variation of gain with different parameters is obtained and the values of these parameters are optimized to achieve a maximum value of gain. A two-stage gain-flattened EDFA consisting of two EDFAs in series is also simulated. In the operating range of 1565-1610 nm, the flat gain of 46 dB is obtained. (C) 2008 Elsevier GmbH.
