Measurement System of the Fibers' Verdet Constant Including a Faraday Rotator Mirror

In order to measure the fibers' Verdet constant without the influence of the linearly birefringence in the test fiber, a system including a Faraday Rotation Mirror (FRM) is proposed and experimentally validated. The effect of the FRM is given theoretically, and the system is built to measure the single mode fiber's Verdet constant which is 0.55±0.01rad/T/m. By experiments, the system is also demonstrated that it owns good reliability and stability.
