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.
