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 fitting the curve of Raman gain spectrum of tellurium-based fiber to the curve of non-dispersive limitation of SR-Stimulated Raman Scattering (SRS) in fiber, The wavelength conversion is numerically simulated, and the factors affecting Raman wavelength conversion are analyzed. At the same time, the Raman wavelength conversion is compared with that of ordinary Si - based fiber. The results show that in the case of using the same power pump signal light, the fiber length of Raman wavelength conversion using tellurium-based fiber is shorter and the peak conversion efficiency is higher than that of ordinary silicon fiber.
