光孤子传输特性模拟 在光纤通信中，光脉冲信号在光纤中传输的过程中会受到色散、损耗和非线性等作用的影响而不断地发生演化和畸变。脉冲演化的规律遵循非线性薛定谔方程（NLSE）。由于NSLE 在一般情况下无法求得它的解析解，因此通常需采要用数值方法来求解，最终归结于求解归一化的NLSE。本文使用了分步傅里叶方法对归一化NLSE 进行了求解，并模拟了输入为一到三阶双曲正割光脉冲条件下光脉冲传输演变情况。(soliton In optical fiber communications, the optical pulse signals in fiber-optic transmission process will be subject to dispersion, loss and non-linear effects, such as constant evolution and distortion occurs. Pulse to follow the evolution of the law of nonlinear Schrö dinger equation (NLSE). Because NSLE under normal circumstances can not achieve its analytical solution, it normally takes mining use numerical methods to solve, and ultimately attributed to solving normalized NLSE. This article uses the step-by-step Fourier method and normalized NLSE was solved, and analog input for the first-order,second-order and third-order hyperbolic secant optical pulses under the conditions of the evolution of optical pulse transmission.)
