PM Optical Circulator
An optical circulator is a device that transmits light in one direction only. Input light enters the circulator from input port 1 and exits from the second port; likewise, light entering the circulator from the second port is reflected and exits from the third port. Functionally, a circulator is similar to a one-way mirror. Shanghai Hanyu's three-port polarization-maintaining optical circulators use PM fiber input and output, featuring high extinction ratio and high isolation, with excellent performance as ideal devices for PM optical systems. The internal structure of a PM circulator includes a polarizing beamsplitter, Faraday rotator mirror, polarizer, etc., to ensure that the polarization state of the light propagates along the slow axis of the PM fiber. PM circulators have important applications in many fields such as high-precision fiber sensing and high-speed communication systems.
