摘　　要：文中阐述了光纤光栅的分类以及它们的特点和应用,根据光的耦合模理论应用MATLAB仿真均匀周期布喇格光纤光栅反射率透射率特性和非均匀啁啾光纤光栅反射率透射率特性,研究得到均匀周期布喇格光纤光栅和非均匀啁啾光纤光栅的反射率、透射率与光栅长度L成正比,L=10mm时反射率和透射率接近100%,对比得到均匀周期布喇格光纤光栅反射率透射率,啁啾光纤光栅具有较宽的反射谱透射谱。研究结论为均匀非均匀光纤光栅器件制作提供理论依据。This paper describes the classification of fiber gratings and their characteristics and application of the coupled mode theory, based on light using MATLAB simulation of uniform fiber Bragg grating reflectance and transmittance properties and nonuniform chirped fiber grating reflectance and transmittance characteristics, research of uniform fiber Bragg grating and non - uniform chirped fiber grating reflectivity, transmissivity and the grating length is proportional to L, L = 10mm reflectivity and transmissivity of close to 100%, in contrast to get uniform fiber Bragg grating reflectance and transmittance, the chirped fiber grating has a wide reflection spectrum transmission spectrum. The conclusion of the study is uniform and non - uniform fiber grating devices and provide a theoretical basis.
