An apparatus and associated method for altering the propagation constant of a region of deflecting propagation constant in an optical waveguide. The method comprising positioning an electrode of an electrode shape proximate the waveguide. A region of deflecting propagation constant is projected into the waveguide and corresponds, in shape, to the electrode shape by applying a voltage to the shaped electrode. The propagation constant of the region of deflecting propagation constant is controlled by varying the voltage that adjusts a deflection angle applied to an input optical signal flowing through the waveguide.
