All optical wavelength conversion for stimulated Raman scattering based on photonic crystal fiber

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.
