摘要

为了进一步提高二阶拉曼光纤放大器的性能指标，对二阶拉曼光纤放大器的主要参数进行了分析。首先，设计了一种可由光开关控制并在传统二阶和传统一阶RFA两种模式之间切换的结构模型。仿真结果表明，二阶RFA可以提高系统增益，改善噪声性能。优化了一阶射频放大器的增益性能。优化的目标是降低平面度。采用粒子群优化算法对泵浦光的波长和功率进行优化配置。经过进一步的结构改进，在100 nm带宽下获得了增益为24.50 dB、增益平坦度为0.98 dB的二阶RFA。这些结果为今后设计性能更好的二阶RFA提供了参考。

Research on second-order Raman fiber amplifier based on particle swarm optimization

In order to further improve the performance index of second-order Raman fiber amplifier, the main parameters of second-order RFA were analyzed. First, a structural model that can be controlled by optical switches and switched between two modes of traditional second-order and traditional first-order RFA is designed. It is proved through simulation that second-order RFA can increase the system gain and improve noise performance. The gain performance of first-order RFA is optimized. The optimization goal is to reduce the flatness. The particle swarm optimization algorithm is used to optimize the configuration of the wavelength and power of the pump light. After further structural improvement, a second-order RFA with a gain of 24.50 dB and a gain flatness of 0.98 dB were achieved in a 100 nm bandwidth. These results provide a reference for the design of second-order RFA with better performance in the future.
