Polarization Maintaining Optic Fiber Couplers

Polarization maintaining Optic Fiber Coupler

Polarization maintaining fiber coupler is a key device to realize linearly polarized light coupling, splitting and multiplexing. Its biggest feature is that it can stably transmit two orthogonal linearly polarized lights, and can keep their respective polarization states unchanged, so it is widely used in various military interferometric sensors, coherent optical communications, fiber optic gyroscopes, and fiber optic hydrophones. critical optics required.

Polarization maintaining coupler or splitter is based on fused taper or planar waveguide technology, which belongs to power division device. The use of polarization maintaining fiber can stably transmit two orthogonal linearly polarized lights and keep their polarization states constant. This product is widely used in WDM and FTTX systems.
