分布式的极化在维持极化的纤维联合能被使用白轻米切尔森干涉仪检测。这种技术通常要求一个仅仅极化模式是激动的。在实际测量,注射极化方向不管多么不能确切被排列到 PMF 的主要斧子之一,因此极化扑灭比率的影响应该被考虑。基于联合理论的极化,测量结果上的事件极化扑灭的影响被评估并且分析,并且当两二直角的 eigenmodes 是激动的时,为联合察觉的分布式的极化的一个方法被开发。
Distributed polarization coupling in polarization-maintaining fibers can be detected by using a white light Michelson interferometer. This technique usually requires that only one polarization mode is excited. However, in practical measurement, the injection polarization direction could not be exactly aligned to one of the principal axes of the PMF, so the influence of the polarization extinction ratio should be considered. Based on the polarization coupling theory, the influence of the incident polarization extinction on the measurement result is evaluated and analyzed, and a method for distributed polarization coupling detection is developed when both two orthogonal eigenmodes are excited.
