摘　　要：为了提高光通信系统的传输效率和降低网络阻塞率,利用光纤中受激拉曼散射(Stimulated Raman scattering,SRS)效应,对全光多路波长转换器提出一种改进。通过SRS效应的耦合波方程解析解,设计实现一路转四路的全光多路波长转换器,再结合拉曼光纤放大器(Raman Fiber Amplifier,RFA)增益平坦化方法,在多路波长转换器的基础上级联一段补偿光纤,前增益后补偿,实现输出信号光功率的平稳。仿真结果表明此方法可行。In order to improve the transmission efficiency of optical communication system and to reduce the network blocking rate, an improved method based on Stimulated Raman scattering by using All Optical Wavelength Conversion is proposed in this paper. The proposed method firstly use the analytical solution of SRS coupled wave equation to design the all-optical multiple wave- length conversion. This wavelength conversion can achieve wavelength convert from one channel to four channels. Then this wavelength coversion is cascaded with a compensated fiber to employ the gain-compensation in RFA in order to get one fixed power output value at the output end. In this way, the output-power flattening is achieved. The simulation results show that this method is convenient and feasible.
