Abstract
L'invention se rapporte à un commutateur optoélectronique ("Opsistor") susceptible d'être commandé par différentes parties du spectre optique et capable de fournir des fréquences permettant une commutation rapide. Ce commutateur qui est fabriqué sous la forme d'un circuit intégré monolithique comporte deux photodiodes parallèles inverses, très rapprochées, de préférence disposées sur un substrat en silicium monolithique, de sorte que l'anode d'une photodiode est électriquement reliée à la cathode de la seconde électrode par l'intermédiaire d'un premier conducteur et la cathode de la première électrode est électriquement reliée à l'anode de la seconde photodiode par l'intermédiaire d'un second conducteur. L'état tension-phase de ce commutateur "opsistor" est déterminé par l'éclairage relatif des deux photodiodes et peut être rapidement commuté. Ce commutateur "opsistor" peut être mis en oeuvre dans des optocoupleurs à grande vitesse, des détecteurs de positions optiques linéaires, des détecteurs de cibles et de contours, des détecteurs pour la reconnaissance d'images, des sous-unités de base d'ordinateurs à états optiquement définis et des codeurs optiques à haute résolution.
