Polarization-maintaining fibers

Polarization-maintaining (PM) fibers rely on the fact that an intentional birefringence introduced in the fiber will maintain two polarization modes that propagate along the fiber distinctly. In order to transmit this polarized light, a passive fiber with the same PM properties is needed.

Coractive develops a wide range of passive PM fibers that match their active fiber in order to minimize losses caused by mismatching.
