polarization beam splitter (PBS) component prism, a Faraday rotator and a second PBS component prism, the first PBS component prism consists of two PBSs arranged oppositely, the second PBS component prism consists of a PBS and a high reflectivity mirror or a PBS arranged oppositely, a half-wave plate is further arranged between the first PBS component prism and the Faraday rotator or between the Faraday rotator and the second PBS component prism, and 3 ports are formed by the structure, wherein lights of a first port pass through the optical rotator and are then outputted by a second port andlights of the second port pass through the optical rotator and are then outputted by a third port. The optical rotator of the invention is designed by using the principles of microoptics of a free space, has fewer components and a simple and compact structure, is easy to be integrated, can be widely applied in a high-speed optical transceiver module and has a good application prospect. 本发明公开了一种光环行器，包括沿光路依序设置的第一PBS组合棱镜、法拉第
