【摘要】 利用由麦克斯韦方程组直接导出的统一耦合模理论分析各种类型的含布拉格光栅的对称光纤耦合器的传输特性。与以前发表的分析方法不同 ,对于含布拉格光栅的耦合区域 ,统一耦合模理论同时考虑了布拉格光栅和耦合器的耦合作用。模拟结果证明它能精确地模拟和解释各种类型的含布拉格光栅的对称光纤耦合器的有关实验现象。更多还原

【Abstract】 The unified coupled mode formalism derived from Maxwell′s equation is employed to analyze the Bragg grating assisted optical fiber symmetric couplers. In the theoretical analysis, the coupling effects due to Bragg grating and coupler are both considered in the Bragg grating region, which is distinct from the previous published approaches. The simulating results verify that the theory can give more accurate explanation to various experimental phenomena.更多还原
