摘要

密集波分复用（DWDM）的发展对放大器的要求越来越高

多波长光纤喇曼放大器（MW FRA）解决了放大带宽的问题

但由于多泵浦喇曼放大过程的复杂性

很难控制增益谱线的平坦度。文章分析了MW FRA的泵浦和信号功率耦合方程

推导出增益表达式。比较了两种优化算法的优劣

并使用遗传算法对泵浦进行了优化

获得了较平坦的增益谱。

Abstract

The development of DWDM presents ever higher requirements for amplifier. The emergence of MW-FRA broke the limit of bandwidth of amplifier

while it put forward a new problem of gain flatness control. This paper analyzed the power coupling equation of pump and signal in MW-FRA

derived its gain formula

then optimized the pump power using inheritance arithmetic

and achieved an improvement on flatness of gain spectrum.
