熔锥直线型3×3单模光纤定向耦合器的光功率耦合分析

Analysis of coupling power for fused-biconical linear format 3×3 single mode optical fiber directional coupler

本文利用组合波导理论对熔锥直线型3×3单模光纤定向耦合器中的光功率耦合行为进行了详细的分析,并对该种耦合器的中心端光纤和旁边端光纤注入光能分别进行了讨论,前者得到了预期的结果,后者的结果与前者不同,却是十分有用的.这两种分析结果与实验结果相符.

This paper desoribera the behavior of coupling power for fused biconioal linear format 3×3 single mode optical fiber directional coupler using the theory of composited waveguides. The conditions of the cental port input and the outside port input in this coupler are discusses respectively. The expected results are obtained in the case of former, but different results in the case of latter, which is very useful. The analysis for these cases are in a good agreement with experimental results.
