Abstract
Disclosed are methods and apparatus for providing endless transformation of the polarization of light. A polarization splitter splits light having an input polarization into beams having substantially orthogonal polarizations. The beams are provided as substantially copolarized to a pair of optical waveguides which are selectively optically coupled. Electrodes apply selected electric fields to the optical waveguides for providing transformation of the input polarization to a selected output polarization. The outputs of the optical waveguides are provided as substantially orthogonally polarized to a combiner for providing a beam of output light having the selected output polarization.
