本文介绍了由传输矩阵计算光纤光栅特性的方法，并应用该方法分析了不同切趾形式的Bragg光纤光栅反射谱，变周期光纤光栅的反射谱和色散特性，相移光栅以及取样光栅的反射谱。得出了光栅参量对其特性的影响规律，并用实验验证了切趾光栅、取样光栅的理论分析。

In this paper a method using transfer matrix is introduced to calculate the spectra of fiber gratings.With this method the authors analyze the reflective spectra of FBG with different aperdization,ph a se-shift gratings and sampled gratings,and also dispersio n specialty of chirped grating.The effects of grating parameters on the grating specialties were observed.In the end we testified the theory analy sis on aperdized gratings and sampled gratings by experiments.
