Polarization-maintaining optical fiber
In telecommunication, a polarization-maintaining optical fiber (PM) is an optical fiber in which the polarization planes of lightwaves launched into the fiber are maintained during propagation with little or no cross-coupling of optical power between the polarization modes.
Note 1: Cross sections of polarization-maintaining optical fibers range from elliptical to rectangular.
Note 2: Polarization-maintaining optical fibers are used in special applications, such as in fiber optic sensing and interferometry. Synonym: polarization-preserving (PP) optical fiber.
