The present invention provides for polarization independence in electrooptic waveguides. Specifically, in accordance with one embodiment of the present invention, an electrooptic waveguide for an optical signal is provided. The waveguide comprises a plurality of control electrodes, an optical waveguide core defining a primary axis of propagation, and an electrooptic cladding at least partially surrounding the core. The control electrodes are positioned to generate a contoured electric field across the cladding. The cladding is poled along a poling contour. The contoured electric field and/or the poling contour are asymmetric relative to a plane intersecting the waveguide core and extending along the primary axis of propagation. The electrooptic cladding defines at least two cladding regions on opposite sides of the waveguide core. The contoured electric field comprises (i) a vertical electric field component within a first one of said pair cladding regions that is larger than a vertical component in a second one of the cladding regions and (ii) a horizontal electric field component within the first cladding region that is smaller than a horizontal component in the second cladding region.
