Title (EN) PHOTOCONDUCTIVE SWITCH PACKAGE
(FR) BOÎTIER D'INTERRUPTEUR À PHOTOCONDUCTION
Abstract:
(EN) A photoconductive switch is formed of a substrate that has a central portion of SiC or other photoconductive material and an outer portion of cvd- diamond or other suitable material surrounding the central portion. Conducting electrodes are formed on opposed sides of the substrate, with the electrodes extending beyond the central portion and the edges of the electrodes lying over the outer portion. Thus any high electric fields produced at the edges of the electrodes lie outside of and do not affect the central portion, which is the active switching element. Light is transmitted through the outer portion to the central portion to actuate) the switch.
(FR) L'invention concerne un interrupteur à photoconduction formé d'un substrat comprenant une partie centrale constituée de SiC ou d'un autre matériau photoconducteur, et une partie extérieure constituée de diamant CVD ou d'un autre matériau approprié entourant la partie centrale. Des électrodes conductrices sont formées sur des faces opposées du substrat, lesdites électrodes s'étendant au-delà de la partie centrale, et les bords des électrodes reposant sur la partie extérieure. Ainsi, tout champ électrique intense quelconque produit aux bords des électrodes s'étend à l'extérieur de la partie centrale, qui est l'élément actif de commutation, et n'affecte donc pas cette partie. La lumière est transmise à travers la partie extérieure jusqu'à la partie centrale afin d'actionner l'interrupteur.
