Abstract

See full text

A polarization controller is configured to control polarization of an optical signal. The polarization controller includes a first polarization rotator and a second polarization rotator controllable by control settings. The polarization controller includes a monitor unit configured to generate a monitoring value indicating a performance of the polarization controller. The polarization controller is configured to determine from the monitoring value if the polarization controller is operating in a selected one of a plurality of optimal performance states. If operation is not in an optimal performance state, the polarization controller is further configured to select different control settings to select an alternate one of the plurality of optimal performance states for the polarization controller.
