采用非对称五层光波导模型，分析了光纤布拉格反射滤波器特性，讨论实现窄带和宽带高反射滤波器的结构参数．文中报道关于光纤布拉格反射滤波器的实验研究，包括制作工艺和测试方法．典型的光纤布拉格反射滤波器在１．５μｍ波段的反射率达８０％，带宽１．５ｎｍ． The asymmetric five-layer optical waveguide model is used to analyze the characteristics of fiber Bragg reflection filters, and the structural parameters of narrow-band and broadband high-reflection filters are discussed. The article reports on the experimental study of fiber Bragg reflection filter, including the production process and test methods. A typical fiber Bragg reflection filter has a reflectivity of 80% and a bandwidth of 1.5 nm in the 1.5 μm band.
