摘　　要：通过对碲基光纤拉曼增益谱曲线进行线性拟合,利用光纤中N信道前向瞬态受激拉曼散射效应(SRS:Stimulated Raman Scattering)的非色散限制的分析理论对碲基光纤拉曼波长转换进行了数值模拟,并对影响拉曼波长转换的因素进行了分析,同时与普通硅基光纤拉曼波长转换进行了比较。结果表明:在采用同样功率泵浦信号光的情况下,较普通硅光纤波长转换而言,利用碲基光纤进行拉曼波长转换采用的光纤长度较短,且得到的峰值转换效率高。By making linear fitting on the tellurium-based fiber-optic Raman gain spectrum,numerical simulations were carried out on tellurite-based fiber Raman wavelength converter based on the theory of N-channel non-dispersive limit transient stimulated Raman scattering（SRS）.A comparison was also made on tellurite-based fiber Raman wavelength converter with conventional silicon fiber Raman wavelength converter.The results show that with the same power of pump signal light,the fiber length of the tellurite-based fiber Raman wavelength converter is shorter and the peak conversion efficiency is higher compared with conventional silicon-based fiber converters.
