摘　　要：为适应下一代6G通信网络对光通信网络提出的高速率、宽带宽和大容量的需求,对拉曼光纤放大器(Raman fiber amplifier,RFA)泵浦参数的优化设计成为了当前光通信系统研究的重点。本文以掺铒碲基光纤为传输介质,提出了一种改进的海洋捕食者算法(modified marine predator algorithm,MMPA),利用该算法优化设计了多泵浦RFA,有效实现了对C+L波段内各信道的平坦光放大。与现有RFA优化算法进行对比,MMPA具有性能优异和鲁棒性强等特点,能有效解决拉曼耦合波方程中的非线性和组合优化等问题,确保RFA的高增益和低增益平坦度。仿真结果表明,在1530—1630 nm的增益谱宽范围内,放大器的平均增益为42.36 dB,增益平坦度为0.67 dB。To meet the high speed,wide bandwidth,and large capacity requirements proposed by the next-generation 6G communication networks for optical communication networks,the optimal design of pumping parameters for Raman fiber amplifier(RFA)has become the focus of current research in optical communication systems.In this paper,using erbium-doped tellurium-based fiber as the transmission medium,a modified marine predator algorithm(MMPA)is proposed to optimize the design of the multi-pump RFA,which effectively achieves the flat optical amplification for each channel in the C+L band.Compared with the existing optimization algorithms for RFA,the MMPA has the characteristics of excellent performance and strong robustness,which can effectively solve the problems of nonlinearity and combinatorial optimization in the Raman coupled wave equation and ensure the high gain and low gain flatness of the RFA.The simulation results show that the average gain of the amplifier is 42.36 dB and the gain flatness is 0.67 dB in the gain spectral width range of 1530—1630 nm.
