摘要
利用变分方法，导出了双曲正割型光孤子在非线性光纤耦合器中传输时满足的动力学方程组，分析了该方程组的平衡点性态，讨论了光孤子的开关特性．指出参数卜Ｋ２。是能实现完全的开关操作的必要条件．
Dynamic equations of solitons propagating in a nonlinear optical fiber coupler have been obtained by using various method. Characteristics of equivalent points are analyzed, and switching properties of optical solitons are discussed in detail. It is pointed out that the necessary condition for perfect soliton switching operation is |β｜ ＜2Д.
