【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.更多还原
