self-phase modulation (spm)造句

In dwdm , the nonlinear effects such as self - phase modulation ( spm ) , cross - phase modulation ( xpm ) become important
然而多波长的密集传输使得光纤中的非线性效应(自相位调制、交叉相位调制等)显著增强。
We derive an analytic expression of the group velocity dispersion ( gvd ) induced chirp and the self - phase modulation ( spm ) induced chirp in the normal dispersionregion of non - kerr - like optical fibers with saturable nonlinarity . the evolution of chirp is simulated by numerical methods . the studied results show that the more powerful saturable effects , the smaller is chirp and the gently is chirp . the net chirp is zero in the central region of the pulse
从理论上推导出具有饱和非线性的非克尔光纤正常色散区内，群速度色散效应导致的啁啾和自相位调制效应导致的啁啾解析表达式.利用数值解法模拟了非克尔光纤正常色散区啁啾演变过程.研究结果表明：当非克尔光纤的饱和非线性增强时，净啁啾不断减小，而且，越来越平缓，脉冲中心附近区域净啁啾接近零
It's difficult to find self-phase modulation (spm) in a sentence. 用self-phase modulation (spm)造句挺难的
