Abstract
A waveguide and method for controllably altering an optical phase delay (OPD) of light traveling along a propagation direction through the waveguide. Many embodiments are disclosed, and in one example, a waveguide may include a core for guiding the light through the waveguide; at least one cladding adjacent the core, wherein the at least one cladding has liquid crystal molecules disposed therein; at least one electrode for receiving a first voltage for controllably altering the optical phase delay of the TE polarized light traveling through the waveguide; and at least one electrode for receiving a second voltage for controllably altering the optical phase delay of the TM polarized light traveling through the waveguide.
