光纤放大器增益锁定动态均衡 fiber amplifier gain clamped dynamic equalization

摘要

在光纤放大器内部同时建立增益谱锁定与平坦机制,研制出适合WDM网络应用的全光锁定高增益、大功率掺铒光纤放大器(EDFA)。在23 dB输入功率动态范围(-40～-17 dBm)内的增益箝制在33 dB,对应总输入功率为-17 dBm的输出光功率为16 dBm,锁定的-1 dB增益带宽为14 nm(1547～1561 nm)。

Abstract

An all optical gain clamped and flattened fiber amplifier is reported. This technique is applicable for WDM networks with dynamic gain equalization of high gain, high power EDFAs. The dynamic range reaches 23 dB (-40~-17 dBm) for a constant 33 dB gain, while the -1 dB gain bandwidth is 14 nm (1547~1561 nm). The output signal power is 16 dBm.
