During the drawing process of polarization-maintaining fiber, when linearly polarized light is transmitted along one characteristic axis of the optical fiber, part of the light signal will be coupled into another characteristic axis perpendicular to it, which will. During the drawing process of polarization-maintaining fiber, when linearly polarized light is transmitted along one characteristic axis of the optical fiber, part of the light signal will be coupled into another characteristic axis perpendicular to it, which will. Therefore, it is important to align the polarization axis of the laser source exactly with that of the fiber, for example using the Polarization Analyzer SK010PA. PM fibres are typically used in interferometers, sensing solutions. Polarization-Maintaining Optical Fiber (PMOF) is a specialized optical fiber that maintains the stable polarization state during optical transmission by enhancing birefringence. There are several PM fiber designs – all quite different and each with its own complexities in preform.
