摘　　要：借助于著名的齐次平衡原理和F-展开法的基本思想,研究非线性光纤方向耦合器系统中的非线性薛定谔方程组,得到满足传输方程的多种Jacobi椭圆函数周期波解和亮孤子解,并通过图形分析法,讨论其中一些解的动力学行为。In this paper, the F-expansion and homogeneous balance method are used to solve the nonlinear optical fiber coupler Schodinger equations. With this method, many kinds of explicit and exact traveling wave solutions are acquired, including Jacobi doubly periodic solutions and bright soliton. Besides, the dynamic behaviors of some solutions are discussed by direct computer simulations
