Abstract

A flat-gain EDFA is demonstrated using Erbium doped gain medium of high concentration on a host medium of silica-based fiber. The suggested EDFA model, using Matlab, shows uniform gain over the varying wave-lengths. The parameters of input signal power, pump power and length are optimized for a maximum EDFA length of 1.5m in the C-band and 9m in the case of L-band. The seamless gain features both for C-band and L-band from modeling are supported by closely experimental validation results. The overall gain remains more or less flat over a spectrum ranging from 1525ηm to 1605ηm with a gain variation of ±3dB, a behavior matching that of a band-pass filter in the time domain.
