Abstract

Pour réduire la puissance consommée et la diaphonie, lors de la transmission de signaux optiques à large bande sans conversion préalable en signaux électriques, dans un commutateur thermo-optique, deux guides d'ondes (WL1 et WL2) s'étendant l'un à côté de l'autre de façon très rapprochée sur leur longueur d'interaction (L) sont au moins partiellement recouverts, sur leur largeur, par au moins une paire de bras en forme de lamelles de l'électrode de chauffage (E), reliés par une pièce jointive (G) commune. La forme de ces bras d'électrode correspond à la géométrie des guides d'ondes (WL1 et WL2) se trouvant en-dessous et au moins un bras d'électrode d'une paire de bras d'électrode est attaqué électriquement.
