Based on the introduction of equivalent phase shift superstructure fiber Bragg gratings(EPS-SSFBG),a method of quantitative analysis of the relationship between EPS-SSFBG and optical pulse width is presented.

• 在介绍等效相移超结构光纤光栅编解码器原理的基础上,提出分析等效相移超结构光纤光栅编解码器的结构参数与光源脉冲宽度关系的定量分析方法,利用MATLAB对光源占空比对于编解码器性能的影响进行了计算机仿真。
