Abstract
A multilayer electrode structure is deposited on or supported in intimate contact with an electro-optic element to define a substantially continuous, transformation-free, branching, fringe field controlled electro-optic waveguide. Transformations are minimized because the fringe field induced waveguiding channels all have substantially equal widths and depths, and discontinuities are reduced by providing bridging electrodes to span any gaps that might otherwise exist in the fringe fields.
