一阶孤子和高斯准孤子在传输中相互作用的研究

Study of the interaction of solitons and Gaussian quasi-solitons in propagation

用分步傅里叶变换法求解光孤子NLS方程 ,研究了一阶孤子和高斯准孤子在传输中相互作用和演化规律 ,发现一阶孤子和高斯准孤子相互作用的结果不仅与脉冲的种类有关 ,且与它们在传输中的排列方式有关 .当以两个一阶孤子 (左右 )和一个高斯准孤子 (中 )的方式混合输入时 ,3个脉冲发生一次碰撞后便逐渐分离 。

The interaction of solitons and Gaussian quasi-solitons in propagation is studied by solving the NLS equation. The results of the propagation depend on not only the types of soliton but also the transmitting ways. In a special way of propagation the problem of signal interaction can be solved.
