Abstract
An apparatus and associated method for altering the propagation constant of a region of changable propagation constant in an optical waveguide. The method comprising positioning an electrode of a prescribed electrode shape proximate the waveguide. An altered region of changable propagation constant is projected into the waveguides that correspond, in shape, to the prescribed electrode shape by applying a voltage to the shaped electrode. The propagation constant of the region of changable propagation constant is controlled by varying the voltage.
