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.


Corning® PM*

Polarization Maintaining (PM) fibers are designed with high performance properties including excellent birefringence and low attenuation. Corning offers the broadest portfolio of PM fibers from wavelengths of 400-1550nm and designs such as High NA and Flame Retardant coatings.
