An apparatus and associated method for altering the propagation constant of a region of changeable propagation constant (190) in an optical waveguide (106). The method comprises positioning an electrode (120) of a prescribed electrode shape proximate the waveguide (106). An altered region of changeable propagation constant (190) is projected into the waveguides (106) that correspond, in shape, to the prescribed electrode shape by applying a voltage (202) to the shaped electrode (120). The propagation constant of the region of changeable propagation constant (190) is controlled by varying the voltage (202).

L'invention concerne un appareil et un procédé associé permettant de modifier la constante de propagation d'une zone de constante de propagation variable d'un guide d'onde optique. Ce procédé consiste à positionner une électrode de forme prescrite à proximité du guide d'onde. On projette, dans les guides d'ondes, une zone modifiée de la constante de propagation variable dont la forme correspond à la forme d'électrode prescrite par application d'une tension sur l'électrode façonnée. Pour commander la constante de propagation de la zone de la constante de propagation, on fait varier la tension.
