Description: 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.

Description: 这个程序只合适计算k=1 (也就是Lcd=1）,对于其他k值，一些参数要做适当变化。这也是soliton format 不宜用于非线性耦合开关的一个原因。它使问题复杂化。这个程序是计算孤子格式化下的非线性薛定格方程组，程序中的方程与我们之前的博文提供的程序的方程不同。我们当初做这个仿真的目的，一方面要重复 S. Trillo, S. Wabnitz, E. M. Wright and G. I. Stegman, 在他们论文“Soliton switching in fiber nonlinear directional couplers.” Opt. Lett. Vol.13, No.8, pp672-674(1988) 的仿真结果，以确保我们程序是正确的。另一方面要以己之矛攻己之盾。当时，孤子开关用孤子归一化的非线性薛定格方程描述已经广泛被接受和使用。很多人因为他们孤子开关的工作，也获得了重要的学术地位，要想发一篇跟他们之前的工作不同的观点的文章是很困难的。那些审稿的人，不是他们本人，就是学生或粉丝。图1中的曲线跟我们其它文中的曲线有很大不同，这是因为在这里输入脉冲是bsech(bt),因而输入脉冲的脉宽跟脉冲幅度一起变化，而其他地方我们只考虑脉冲幅度的变化，因为脉宽的变化已经包含在参量Lcd 中了。-This Matlab file solves the nonlinear Schrodinger equation in soliton format Platform: |
