Abstract

L'invention concerne un commutateur optique qui comprend un conduit de lumière dont la section transversale peut être modifiée, un élément piézoélectrique sensible à une lumière d'activation et associé au conduit de lumière, cet élément pouvant être actionné de manière à modifier sa forme lorsqu'il est frappé par la lumière d'activation, et un élément conducteur associé exploitable à l'élément piézoélectrique en vue de renforcer la sensibilité de celui-ci à la lumière d'activation. L'élément piézoélectrique est associé au conduit de lumière et peut être actionné de sorte que les modifications de la forme de cet élément entraînent des modifications suffisantes de la section transversale modifiable du conduit de lumière pour commander le passage de lumière dans ledit conduit. Des portes logiques et une fonctionnalité logique utilisant un commutateur optique sont également décrites.
