摘　　要：以后向泵浦的宽带光纤拉曼放大器为模型 ,基于平均功率的思想 ,运用矩阵迭代法模拟信号光和泵浦光在光纤中的传输特性 ,数值计算出拉曼增益曲线 .这种算法结合了平均功率法的快速和矩阵迭代法的简单易控制的优点 ,在保证计算精度的情况下能提高计算速度 .理论分析结果和实验结果均显示该算法可以准确模拟拉曼放大过程 .Based on the theory of average power analysis, this paper presents a matrix iterative method for the broad bandwidth fiber Raman amplifiers (FRA) with multiple backward pumps. The method can be used to simulate the propagation of signals and pumps in the optical fiber and calculate the gain characters of FRA. It includes two advantages: the high speed of the average power analysis and the simpleness of matrix iteration. With same accuracy the method can save the calculation time. The results of the theoretical analysis and the experiments show that the method can simulate the Raman amplification exactly. It can be used to guide the design of FRA.
