摘要 提出了一种多泵浦反向光纤拉曼放大器(FRA)的新型实用模型,能够给出小信号增益和噪声指数。采用数值计算泵浦光的传播规律,利用此结果解析求解信号光沿光纤的功率演化,解决了泵浦与信号光反向传输的问题。利用拟合图谱通过插值得到拉曼增益系数代替传统的将拉曼增益谱近似为三角形的方法。模型中考虑了泵浦与泵浦、泵浦与信号之间的相互作用,并包含自发拉曼散射噪声。 A new model to calculate the smallsignal optical gain and noise figure of multiwavelength backwardpumped fiber Raman amplifier(FRA) was developed.Complicated target method was replaced by combination of numerical and analytical methods to resolve the problem on forward transmitted signal and backward bump.Raman gain coefficient is drawn from an insert valve of a Raman profile instead of triangle Raman profile approximation.Pumppump and pumpsignal Raman interactions,spontaneous Raman scattering noise were also considered in this model.
