Abstract

In order to solve the problem of traffic congestion and unbalanced utilization of wavelength resources caused by the explosive growth of traffic demand in the next generation mobile communication network. In this paper, a multichannel all-optical wavelength converter with stable output power is designed by using germanium doped microstructure fiber. Based on the theoretical model of stimulated Raman scattering, a multi-channel all-optical wavelength converter is constructed. The waveforms of the pumped signal light and the converted detection light are analyzed, and the influence parameters of gain and flatness are discussed. The simulation results of OptiSystem show that the waveforms of the four-channel detection light and the pump signal are consistent and the output power is basically the same, and the gain fluctuation range is less than ±0.38dB, which verifies the feasibility of the method.
