In-line Polarizer

SENKO’s In-line Polarizer is designed to pass light with one specific polarization while blocking the other polarization with high extinction ratio. It can also be used to enhance the extinction ratio of signals with its excellent polarization properties.

In-line fiber polarizers are created in order to pass linearly polarized light while blocking the orthogonal polarization from an unpolarized light source.

In-line fiber polarizers can be used for various fiber optic network applications. These would include polarization-maintaining fiber amplifiers, high-speed communication systems, fiber lasers and instrumentation.
