We investigate power-dependent phase-matched four-wave mixing (FWM) in wavelength division multiplexing transmission lines, in which positive and negative dispersion fibers are alternately arranged to manage the dispersion and the dispersion slope. The FWM effect shows power-independent phase matching when the channel power is low. However, it is power dependent at high power. The maximum FWM conversion efficiency is shifted away from the zero channel space in the case of power-dependent phase matching. Optimization of the dispersion system for suppression of the FWM effect is determined.
我们研究了波分复用传输线中与功率相关的相位匹配四波混频（FWM），其中正负色散光纤交替排列以控制色散和色散斜率。当信道功率较低时，FWM效应呈现出与功率无关的相位匹配。然而，在高功率时它与功率相关。在与功率相关的相位匹配情况下，最大FWM转换效率偏离零信道间距。确定了用于抑制FWM效应的色散系统的优化方法。
