提出了利用EPP方法分析光纤布拉格光栅中隙孤子的解。基于非线性耦合模式方程(NLCME)定性地分析了无微扰条件下的隙孤子参数与孤子的其它特性的关系。利用EPP方法分析了隙孤子的能量特性。证明了隙孤子的速度影响形态特性和能量分布。从理论上解释了已观察到的一系列隙孤子的试验现象,对光纤布拉格光栅中产生隙孤子的应用具有理论意义。
An EPP method is presented to analyze the soliton in a fiber Bragg grating. Based on the nonlinear coupled mode equation (NLCME), the relationship between the parameters of the soliton without soliton and other properties of the soliton is qualitatively analyzed. The energy characteristics of gap solitons are analyzed by EPP method. It is proved that the velocity of gap solitons affects morphological characteristics and energy distribution. The experimental phenomena of a series of soliton solitons observed in theory are explained theoretically, which has theoretical significance for the application of the generated solitons in fiber Bragg gratings.
