Polarization-maintaining optical fiber

OverviewApplicationsPolarization crosstalkPrinciple of operationDesignsPolarization-maintaining optical fibers are used in special applications, such as in fiber optic sensing, interferometry and quantum key distribution. They are also commonly used in telecommunications for the connection between a source laser and a modulator, since the modulator requires polarized light as input. They are rarely used for long-distance transmission, because PM fiber is expensive and has higher attenuation than single-mode fiber. Another important application is fiber-optic gyroscopes, which are wi
