Polarization-Maintaining Optical Isolator
Polarization-maintaining devices preserve the original polarization state as far as possible, or transform it in a defined way, when joining or coupling polarized light between two polarization-maintaining fibers. Examples include PM connectors, PM collimators, PM multiplexers/demultiplexers, depolarizers/polarizers, polarization-dependent circulators and isolators, and polarization-maintaining optical couplers.
