摘要
给出了描述连续波扰动下飞秒光脉冲在光纤系统中传输的微扰高阶非线性薛定谔方程,通过矩法和微扰理论分析了飞秒亮孤子与连续波相互作用的特性,并利用龙格-库塔积分和分步傅里叶方法进行了数值模拟.结果表明,连续波微扰对光纤孤子通讯系统是十分有害的,在实际通讯过程中应当尽量避免连续波的渗入.
Perturbed higher order nonlinear Schrodinger equation describing the propagation of femetosecond optical pulse in the optical fiber under the perturbation of continuous wave was presented. The interactions between bright optical soliton and continuous wave have been studied by moment method and perturbation theory. Also the numerical evolution by Runge-Kutta and split step Fourier method are given. As a conclusion,the injected continuous wave should be avoided at best since it was harmful to the optical soliton communication.
