摘要

在分析拉曼光纤放大器(RFA)原理的基础上

采用遗传算法对 5波长后向泵浦拉曼光纤放大器的波长和功率进行了优化设计。实验采用位于5个波长处的7个泵浦激光器和100.8 km的色散位移光纤

实现了带宽为90 nm、开关增益为15.55 dB、增益平坦度为0.87 dB的拉曼放大

其平均有效噪声系数为-3.5 dB

与理论分析结果一致。

Abstract

Based on analyzing the principle of the Raman Fiber Amplifier(RFA)

optimal design of a backward pumping Raman fiber amplifier with five different pump wavelengths was carried out. With seven pump lasers at five different wavelengths and a 100.8 km dispersion-shift fiber

a broadband optical Raman fiber amplifier with gain band over 90 nm

on-off gain of 15.55 dB

gain flatness below 0.87 dB and average effective noise coefficient of -3.5 dB was demonstrated experimentally. The experimental results agree with the theoretical calculation.
