光纤中的交叉相位调制不稳定性研究

Guangtongxin yanjiu, 2008
在同时考虑四阶色散和五阶非线性的情况下,以扩展的非线性薛定谔方程为基础,研究了有损光纤中双光束交叉相位调制（XPM）不稳定性。结果表明:由于四阶色散的影响,在光纤的正、反常色散区,XPM所致的调制不稳定性可发生在两个频谱区;正、负五阶非线性的存在分别对XPM不稳定性起加强和减弱作用。

一神非定常振荡流的稳定性分析

, 1996
本文分析了一种非定常振荡的不稳定性问题．其特点是．应用偏微分方程特征理论以及Ｏ－Ｓ方程特征值的展开，求解扰动波的相函数而不是预先给定扰动波的波动形式．本文研究平面Ｐｏｉｓｅｕｉｌｌｅ流与其垂向振荡流的组合流动系统．对于连续振荡源导致的波包演化 ...
