这是一个简单的FFT为无电位1 +1 +1 Ð 薛定谔方程的光束传播方法。如果该软件灵活,允许引入的术语(如果是极少数需要包括色散效应高阶导数)。例如,如果一个人渴望解决的一个方程的形式: (四/ dz的+ Ð ^ 2/dx ^ 2 - 0.25 * Ð ^ 3/dx ^ 3)== 0 Ÿ 它可以解决使用以下代码: Ž = linspace(0,1,512) x = linspace(-5,5,1024) psi0 =进出口(- x的。^ 2) Ð = D_lateral1D(十,2)-0.25 * D_lateral1D(十,3) 字段= LinearBPM(psi0,有D,Z) 凡D_lateral1D是一个函数,提供“取代”的微分算子。 这个函数是在一个非线性的BPM,我曾对(分步,谱方法等),将提交给我,当我完成他们的文件和组织功能更复杂的设置非常初期阶段。 -This is a simple FFT based beam propagation method for potential-free 1+1+1D Schrodinger equation. The software if flexible and allows to introduce high-order derivatives in the term (very handful if is needed to include dispersion effects). For example, if one desires to solve an equation in the form: (d/dz+ d^2/dx^2- 0.25*d^3/dx^3)Y == 0 It can be solved using the following code: z=linspace(0,1,512) x=linspace(-5,5,1024) psi0=exp(-x.^2) D=D_lateral1D(x,2)-0.25*D_lateral1D(x,3) field=LinearBPM(psi0,D,z) Where D_lateral1D is a provided function that "replaces" the derivative operator. This function is a very early stage in a more complex set of non-linear BPM functions that I have made (split-step, spectral methods, etc.) and I will submit them when I finish their documentation and organization. Sorry for my English, I m eager for your comments.

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
