Classification: CPC G  H | IPC G

Claim 7:
8. A reconfigurable polarization rotator array comprising:
a plurality of liquid crystal (LC) microcells, each individual LC microcell separately addressable by a control voltage input to provide one of 90° polarization rotation and 0° polarization rotation, the plurality of LC microcells all exhibiting a same width W less than ten microns;
a plurality of control electrodes coupled to the plurality of LC microcells in a one-to-one relationship; and
a window configuration controller coupled to the plurality of control electrodes and responsive to window reconfiguration commands to apply appropriate voltages to each control electrode of the plurality of control electrodes to define selected groups of adjacent microcells to form a transmission window and provide a predetermined polarization rotation to an optical beam passing through the transmission window.
