摘　　要：为了克服普通波长转换器只能转换单一波长的缺陷,利用可调谐激光器和受激喇曼散射放大器理论,通过对多信道前向瞬态受激喇曼散射耦合方程的解析解进行分析,得出二信道时的增益表达式。建立基于受激喇曼散射的可调谐波长转换技术的理论模型,并利用OptiSystem软件对其进行仿真研究。仿真结果表明,两路光频率差在1～15THz之内的情况下,输出光信号的波长受可调谐激光器的控制,即实现波长转换的可调谐,并且转换后光信号的增益与两路光的频率差成正比,与泵浦光的波长成反比。In order to solve the defect that common wavelength converter can only convert a single wavelength,using a tunable laser and stimulated raman scattering amplifier theory,two channel gain expression is got by analysis the analytic solution of multi-channel coupled equations Transient Stimulated Raman Scattering.A theoretical model of tunable wavelength conversion technology based on stimulated raman scattering is established and simulation is tested by using OptiSystem Software.The simulation results show that under the conditions of two optical frequency differences within 1～15 THz,the wavelength of the output optical signal controlled by the tunable laser can achieve the tuneable wavelength conversion.The gain after optical signal conversion is proportional to the frequency difference of the two lights and inversely proportional to the wavelength of the pumping light.
