Polarization-maintaining fibers

Polarization-maintaining fibers – also known as PM fibers – ensure that the light remains linearly polarized. Selectively induced stress on the fiber core causes birefringences. These, in turn, cancel out interferences between the individual modes in the fiber core so that the polarization of the light waves is maintained.
