摘要
提出一种行之有效的优化算法.该方法在喇曼放大器的功率耦合方程基础上,通过遗传算法和龙格-库塔算法的结合,对分布式宽带光纤喇曼放大器的性能进行了数值仿真模拟,得到了传输距离100 km、带宽70 nm内,平均开关增益为15.2 dB、增益平坦度优于±0.7 dB的优化结果.
Abstract
In this paper,an effective optimization algorithm is proposed.Based on the coupled power equation of the Raman amplifier,a method which combines the genetic algorithm and Runge-Kutla method is used to optimize the performance of the distributed Raman fiber amplifier.By numerical simulation,70 nm bandwidth Raman gain rippled less than 0.7 dB is attained,and the average on-off gain is 15.2 dB through 100 km transmission medium.
