Abstract
Filament optique à gradient d'indice à grande largeur de bande comprenant une couche de gainage extérieure, une couche d'arrêt prévue sur la face interne de celle-ci et une âme en verre de haute pureté à gradient d'indice de réfraction disposée à l'intérieur de ladite couche d'arrêt et accolée à celle-ci de façon à former une interface entre ladite âme et ladite couche d'arrêt, ladite âme étant formée essentiellement d'un verre de base, de B2 O3 et d'au moins un dopant additionnel, la couche d'arrêt comprend du dopant additionnel en quantité sensiblement uniforme sur toute son épaisseur et sous une proportion liée à celle du B2 O3 , l'âme presente à l'interface un indice de réfraction sans variation abrupte et de valeur sensiblement égale à l'indice de réfraction de la couche d'arrêt à l'interface, la quantité de B2 O 3 au sein de l'âme allant en décroissant de l'interface à l'axe central du filament optique. Application aux télécommunications optiques.
