Abstract

L'ELEMENT ELECTRO-OPTIQUE DE MODULATION DE LUMIERE 1 CONFORME A L'INVENTION COMPORTE UN CRISTAL EN FORME DE PLAQUE 2 EN PHOSPHATE DE POTASSIUM HYDROGENE OU DEUTERIE DONT LES FACES SITUEES EN REGARD PORTENT DES ENSEMBLES IDENTIQUES DE COUCHES TRANSPARENTES. VU DE L'INTERIEUR VERS L'EXTERIEUR, UN TEL ENSEMBLE EST FORME PAR UNE COUCHE INTERMEDIAIRE COMPORTANT UNE COUCHE EN OXYDE D'ALUMINIUM 4, 4 ET UNE COUCHE EN BIOXYDE DE SILICIUM, 5, 5 UNE PREMIERE ELECTRODE 6, 6 FORTEMENT OHMIQUE QUI, A TRAVERS UNE COUCHE DE CIMENT TRANSPARENTE9, EST RACCORDEE A UNE DEUXIEME ELECTRODE8, 8 PEU OHMIQUE, AINSI QU'UNE FEUILLE EN VERRE 7, 7 PORTANT CETTE DEUXIEME ELECTRODE. UN TEL ELEMENT DE MODULATION DE LUMIERE DONT LES PROPRIETES OPTIQUES SONT DETERMINEES PAR L'EFFET POCKELS LONGITUDINAL, EST UTILISABLE AVANTAGEUSEMENT DANS LES DISPOSITIFS DE DEVIATION DE LUMIERE TRAVAILLANT EN COMMUTATION A FREQUENCE ELEVEE. APPLICATION: TELECOMMUNICATION.
