测量光隔离器隔离度的新方法

The New Method of Measurement for the Isolation of the Optical Isolator

提出一种测量光隔离器的隔离度的方法，可消除隔离器反射光的影响，并以λ／４片光隔离器进行了测量，取得较好的效果。

The new method of the measurement for the isolation of the optical isolator is presented in this paper. The neglected effect of light reflected by the isolator is eliminted in the tradition methods. Take the quarter-wave plate as an example. this optical isolator is made by ourselves. we obtained the good result.
