飞秒光孤立波解传输的稳定性分析
Stability Analysis of Femtosecond Optical Solitary Wave Solution with Arbitrary Parameters
摘要
针对高阶非线性薛定谔方程任意参量下的飞秒光孤立波解,用数值演化方法考察了该光脉冲在受到各种初始扰动时的稳定性。结果表明:当飞秒光脉冲受到振幅及波形扰动时可以稳定传输,对于随机噪声及啁啾的扰动,在一定范围内也可传输,这有可能为进一步实现飞秒光脉冲在光纤中的无畸变传输提供一定的理论依据。
Abstract
Aiming at a type of femtosecond optical solitary wave solution under arbitrary parameters discovered recently, the stability of the light pulse against some kinds of initial perturbations by employing numerical simulation is investigated. The results show that under the amplitude and wave shape perturbations the femtosecond pulse can propagate in a stable way and under the perturbations of random noise and chirp the light pulse can still propagate to a certain extension. These results will offer a theory support for the distortionless propagation of light pulse in optical fiber.
