摘要
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 characteristics of optical fibre Bragg reflective filter (FBR) are analysed on the bssis of asymmetric five- layer optical waveguuide model, and the structural parameters of FBR are discussed for broad and narrow bsnds with high reflectivity. The experimental studies on FBR are presented in this Paper, including fabricationtechnologies and measurement method. Typical Performances of our FBR devices are as follows: 80% reflectivity and 1. 5 nm bandwidth (FWHM) at 1. 5μm region.
