Experimental Investigation in Isolation Degree Polarization Sensitivity of Fiber Optic Isolator

本文采用了 180°输入测量的新方法研究了光纤隔离器隔离度随着输入线偏振光偏振方向变化。并对其进行了详细的讨论与分析。研究的结果对于该类光纤隔离器的设计和测试具有一定的参考价值。A new method for omnidirectional inputs’ measurement of isolation degree of fiber optic isolator is presented. The results of experiment show that isolation degree changed according to the variation of polarization direction of input linear polarization light. The rationale is analyzed in details. The results are valuable for the design and measurement of this type of fiber optic isolators
