基于光纤中前向瞬态受激拉曼散射效应分析理论,利用光子晶体的高非线性特性,对光子晶体光纤拉曼波长转换进行了数值分析,并建立了全光波长转换设计方案的理论模型,给出了设计原理框图及实现方法。用OptiSystem对四路探测光进行波长转换仿真,仿真结果表明:所设计的全光波长转换器同时对四路探测光实现波长转换,转换输出的信号光码型和输入泵浦信号光码型一致,并且所得到的眼图线迹清晰,"眼睛"张开度良好。论证了该设计方案可行。

The Raman wavelength conversion was studied and numerically demonstrated which was based on the theory of forward transient stimulated Raman scattering in photonic crystal fiber, which has high nonlinear coefficient. Design scheme and implemented method of the theoretical model of all optical wavelength conversion are presented. The simulation was calculated by OptiSystem with 4 continuous probing signals. The simulation results show that the all-optical wavelength converter can convert 4 probing light in the same time, and the output signal light patterns and input pumping signal light pattern have the same waveform. Furthermore, the simulated eye diagram has a clear line and good opening degree. The feasibility is verified by the scheme.
