Polarization-Maintaining Optical Circulator
An optical circulator directs light in one direction: light entering port 1 exits port 2, and light entering port 2 is reflected to port 3. Functionally it resembles a one-way reflecting mirror. Shconnet’s three-port polarization-maintaining optical circulator uses PM fiber inputs and outputs and offers high extinction ratio and high isolation, making it suitable for PM optical-path systems. Its internal components include polarizing beamsplitters, Faraday rotator mirrors and polarizers to ensure that the polarization state propagates along the slow axis of the PM fiber. PM optical circulators are important in precision fiber sensing, high-speed communications and many other applications.
