摘　　要：为了适应下一代6G网络对光纤传输系统大容量、高速率和低时延的要求,以石英光纤为传输介质,利用人工蜂群算法设计了二阶多泵浦拉曼光纤放大器。采用龙格-库塔法和打靶法求解二阶多泵浦拉曼光纤放大器的功率耦合波方程,再通过人工蜂群算法对4个泵浦光的不同排列结构进行优化分析。通过Matlab仿真,从14种双向泵浦结构中,得到了性能最优的双向泵浦结构FFBF,该结构在100 nm带宽范围内的平均增益高达24.8 dB,增益平坦度仅为0.78 dB,为6G网络的拉曼光纤放大器的设计和优化提供了参考。In order to meet the requirements of the next generation 6G network for large capacity,high speed and low delay on optical fiber transmission system,a second-order multi-pumping Raman fiber amplifier is designed by using quartz fiber as transmission medium and artificial bee colony algorithm.The Runge Kutta method and the shooting method are used to solve the power coupled wave equation of the second-order multi-pumping Raman fiber amplifier,and then the artificial bee colony optimization algorithm is used to optimize the different arrangement structures of the four pumping beams.Through Matlab simulation,the best bi-directional pumping structure FFBF is obtained from 14 types of bi-directional pumping structures.The average gain of the structure is as high as 24.8 dB in the bandwidth of 100 nm,and the gain flatness is only 0.78 dB,which provides a reference for the design and optimization of Raman fiber amplifier in 6G network.
