| 摘 要： | 基于光纤光栅在光通信中的重要应用,根据耦合模理论数值模拟了波长在1.55μm附近时光纤光栅长度与反射率的关系,分析图形得到了在1.50μm到1.55μm之间出现较强的反射率,几乎接近100%,同时分析了折射率变化对反射率的影响,研究结果为光通信中无源光器件的制作提供理论依据。

| Abstract: | Based on application of fiber grating for optical communication,the relationship between fiber grating length and the reflectivity in the 1.55μm wavelength were imitated based on the datas of coupled mode theory.There was strong reflectivity in the range of 1.50μm to 1.55μm,which almost close to 100%.The influence of variation of refractive effect on reflectivity was analyzed.The results provided theory basis for the passive optical components in optical communications device design. |
