| 摘 要： | 传统双级光隔离器45°装配无法达到隔离度最优化问题。从双级光隔离器的光学结构和工作原理入手,分析了双级光隔离器的插入损耗、反向隔离度,以及偏振相关损耗,使用MATLAB定量分析了双级隔离器装配存在偏转角度误差时的插入损耗和反向隔离度,为双级隔离器装配的最佳化提供了理论上应保证44°装配这一可行的保障方法。 |

| Abstract: | Traditionally, the dual-stage optical isolator assembled by 45°cannot fit isolation optimization. To solve this problem, from describing the principle and conformation of the dual-stage optical isolator, the insertion loss, the isolation, and the polarization dependent loss are analyzed.A quantitative analysis of the insertion loss and the isolation is given by using MATLAB, when the dual-stage optical isolator assembly has deflection angle error. A feasible method is provided for the dual-stage optical isolator′s optimal assembly by ensuring angle 44°. |
| Keywords: | optical devices isolator insertion loss isolation polarization dependent loss error analysis |
