摘　　要：提出了用连续泵浦光在硅波导中的受激喇曼散射对信号光进行放大的方法.建立了信号光和泵浦光在硅波导中传输的耦合方程,得到了计算信号光增益的理论模型.利用数值模拟结果,对泵浦功率沿波导的分布,信号光在不同波导长度以及输入功率情况下的增益等进行了分析和讨论.结果表明,适当增加波导长度和泵浦光功率可以得到较高喇曼增益的结论.signal wa A ve signal wave method ab be amplifi the pump out stimulated Raman scattering（SRS） in the ed by a continuous pump wave,is presented. wave transmissed in the silicon waveguide and ilico The n waveguide, with coupled equation model of the gain which the about the of signalwave in theory were constructed, According to the model resuh,the gain of signal wave responsing to the variation of the waveguide length and pump power was analyzed, The conclusion that Rarnan gain can be raised by increasing the waveguide length and pump power properly was show,
