摘　　要：以耦合模理论为基础 ,采用分段均匀和传输矩阵法 ,得到分析啁啾非均匀光纤光栅光谱特性的教学物理模型 ,讨论了啁啾系数对高斯型切趾光栅和相移光栅滤波特性的影响。Based on coupled-mode theory, the theoretical model of linearly chirped nonuniform fiber Bragg gratings(FBG) have been set up by using piece-uniform method and transferring matrix approaach. The impact of chirp parameter on reflection charateristics of Guassian apodized and phase-shifted chirped FBG have been discussed.
