1x2 PM Coupler Polarization Maintaining Splitter
The Polarization Maintaining coupler is especially applied in fiber sensor and test instrument systems.
PM fiber is specialty optical fibers with strong built-in birefringence,
preserving the properly oriented linear polarization of an input beam.
About PM fiber
PM fibers have been under development since the 1970s. PM fibers are required when polarization of light is necessary for the application. In telecommunication, they are used in some fiber optic networks where components, such as lithium niobate modulators, can be sensitive to the signal polarization state.
Other applications can be found in fiber optic sensing and interferometry. These fibers enable accurate and stable sensing of physical parameters such as pressure and rotation. For example, fiber optic gyroscopes require PM fiber.
