摘要: 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,从而可克服脉冲间的相互干扰.

Abstract: 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.
