光纤连接器反射特性的研究

Study of Reflectance of Optical Fiber Connectors

主要研究常用的垂直端面连接器的光反射特性。通过测量光纤垂直端面的光反射分析光纤抛光端面上的高折射层厚度与反射比的关系、环境温度与反射比的关系特性；光纤端面不抛光而直接连接时的反射比与温度、空气隙厚度等的关系特性，给出垂直端面上的高折射率层的折射率和厚度计算与测量方法。实验结果与分析相吻合。

In this paper,the reflective characteristics for tow typical contact type connectors of optical fiber are described,mathematical models for fiber optical connectors is presented;The index matching material and the high index layer on the polished fiber endfaces are investigated.The method and caculations formal for the refractive index and thickness of high index layers on perpendicular fiber endfaces is given.The results from experiment agree with caculations.
