摘要
在光隔离器等重要光学器件中，聚焦纤维透镜用作准直器。本文详细分析了在光纤与透镜连接处采用斜端面与采用垂直端面时准直器性能的变化。
In this paper,by using the method of ray tracting and ABCD matrix,we analysize the characteristics of the SML collimator,particularly about the influecne of the angled end face used to increase the Return Loss.We find that the influence is so small to the SMLs Divergence Angle and Insertion Loss that it can be omitted.A more thorough reserch may find that the influence could be larger to some characteristics such as Chromatic.The conclusion drawed in this paper has been verifed by experiments.
