| 摘 要： | 通过对双模光纤的传输方程进行数值求解，从理论上验证了在不考虑群速度失配的情况下，在光纤两个模式上相互作用的非线性色散光波之间，存在着由相交相位调制(CPM)所引起的调制不稳定(Ml)．由理论输出谱线进行分析得出，MI效应产生的参量四波混频(FwM)效应的参量stokes边带和反stobes边带将对普通的受激喇曼散射(SRS)产生明显的抑制，并讨论了输入光功率对此抑制效应的影响．

| Abstract: | By solving numerically the transmission equations in fibers, we testify the existence of cross-phase-modulation-induced modulationaI instability (MI) in the absence of group-velocity mismatch between the interacting waves of two modes. By analysislng the theoretical output spectra of fibers, we draw a conclusion that a parametric four-wave mixing (FWM) process with the MI effects in a two-mode fiber involving parametric Stokes and anti-Stokes sidebands inhabits the growth of the ordinary Raman Stokes radiation. Furthermore, we discuss the influence of the input power on the inhabition effects. |
