Title (EN) TUNABLE INFRARED TRANSMISSION FILTERS WITH PHASE CHANGE MATERIALS
(FR) FILTRES DE TRANSMISSION INFRAROUGE ACCORDABLES AVEC MATÉRIAUX À CHANGEMENT DE PHASE
Abstract:
(EN) A tunable filter is provided that includes a substrate, and an active region that is positioned on the substrate. The active region includes a phase change material having selenium (Se) that allows for switching from an amorphous state to a crystalline state.
(FR) La présente invention concerne un filtre accordable qui comprend un substrat, et une région active qui est positionnée sur le substrat. La région active comprend un matériau à changement de phase comportant du sélénium (Se) qui permet le basculement d’un état amorphe vers un état cristallin.
