摘要
利用自伴算符方法，通过耦会非线性薛定谔方程分析了双芯光纤中孤子脉冲到达检测窗口的时间抖动问题．研究结果表明：双芯光纤的两芯中孤子脉冲走时抖动大小与注入的两孤子间相对相位、注入的孤子振幅及传输距离有密切关系，表现为明显的模式竞争现象，及在耦合传输过程中随传输距离周期性和非周期性的变化规律．
Time jitters in twin-core fiber is analyzed by using self-companying operator method through coupling nonlinear Schrodinger equation. The results show: the time jitters relate closely with the input relative phases, the input amplitude of two solitons and propagation distance. There are apparent mode competition,periodic and non-periodic conduction of the time jitters in twin-core fiber.
