中文说明：
本模拟是采用分步傅里叶的解，求光孤子在光线内传输过程数值求解薛定谔方程。方程是激光器在光纤中传输的过程。
English Description：
< p > In this simulation, the split step Fourier method is used to solve the propagation process of optical soliton in the light, and the Schrodinger equation is solved numerically. The equation is the process of laser transmission in optical fiber.
