Abstract

STRUCTURE DE FILTRE PASSE-BANDE INFRAROUGE ET FILTRE PASSE-BANDE INFRAROUGE UTILISANT LA STRUCTURE L’invention a pour objet une structure de filtre passe-bande infrarouge (20) qui est formée en empilant de manière alternée une pluralité de couches d’hydrure d’aluminium et de silicium (21) et une pluralité de couches de faible indice de réfraction (22). La pluralité de couches de faible indice de réfraction (22) comprend de l’oxyde. La structure de filtre passe-bande infrarouge (20) possède une bande passante qui chevauche au moins partiellement la plage de longueurs d’onde de 800nm-1600nm. La bande passante possède une longueur d’onde centrale, et la longueur d’onde centrale possède une amplitude de décalage qui est inférieure à 11nm lorsqu’un angle d’incidence change de 0° à 30°. L’invention a en outre pour objet un filtre passe-bande infrarouge qui comprend la structure de filtre passe-bande infrarouge (20) formée sur une première surface latérale d’un substrat (10) et une couche antiréfléchissante (30) formée sur une seconde surface latérale du substrat (10) qui est au niveau d’un côté opposé à la première surface latérale.
