Abstract
A Faraday rotator mirror, including: a polarizing beam splitter, a polarizing beam converging device made from birefringent crystal, a Faraday rotator, a reflecting mirror. In operation, light rays from an optical coupling element pass through the polarizing beam splitter, the polarizing beam converging device, the Faraday rotator, and the reflecting mirror, in that order, and then return back through the Faraday rotator, the polarizing beam converging device, and the polarizing beam splitter, in that order, and are output from the optical coupling element in reverse to the original incidence path.
