Abstract
L'invention concerne un commutateur et modulateur optique. Il comporte deux guides d'ondes en matière électro-optique avec un intervalle de couplage, sur une surface d'un substrat. Ces guides d'ondes peuvent supporter des modes de propagation d'ondes optiques dans deux directions de polarisation perpendiculaires entre elles. Un dispositif produisant un champ électrique est positionné de manière que des composantes perpendiculaires se situent dans des parties voisines de l'intervalle de couplage. L'invention s'applique notamment à la commutation des guides d'ondes optiques pour les télécommunications.
