Abstract:
An electrooptic waveguide for an optical signal, said optical signal including a horizontally oriented component TE and a vertically oriented component TM, said waveguide comprising a plurality of control electrodes, an optical waveguide core defining a primary axis of propagation, and an electrooptic cladding at least partially surrounding said core, wherein:said control electrodes are positioned to generate a contoured electric field across said cladding; said cladding is poled along a poling contour; at least one of said contoured electric field and said poling contour is asymmetric relative to a plane intersecting said waveguide core and extending along said primary axis of propagation; and said asymmetry defines a substantially polarization-independent waveguide structure along said primary axis of propagation of said electrooptic clad waveguide.
