摘　　要：矢量空间孤子的形成及其传输是个重要问题。在介绍光折变效应的含义及其理论模型的基础上,给出描述光束传播的方程;通过简化方程组,得出最简单的耦合矢量孤子对,进而研究了该矢量偶极孤子对的传输过程;通过改变入射光束的振幅和宽度,数值模拟了矢量耦合偶极孤子对的形成和传播过程。Formation and propagation vector spatial soliton is an important issue.This paper introduced the meaning of the photorefractive effect and its theoretical model,also the description equation for the beam propagation is given;through simplifying the equations,the simplest coupling vector soliton pairs are obtained,also the propagation of vector dipole soliton is presenented.At the same time,by changing the amplitude and width of the input light beam,we simulate the formation and propagation of the coupled vector dipole solitons.
