Title (EN) HIGH NUMERICAL APERTURE FIBER
(FR) FIBRE DOTÉE D'UNE OUVERTURE NUMÉRIQUE ÉLEVÉE
Abstract: front page image
(EN)An optical fiber comprising: a silica based core having a first index of refraction ni; and at least one silica based cladding surrounding the core, the at least one silica based cladding comprising index lowering non-periodic voids containing a gas, wherein at least 80% of said voids have a maximum cross-sectional dimension of less than 2000 nm, and the NA of the fiber layer situated immediately adjacent to and inside said at least one silica based cladding is at least 0.2.
(FR)La présente invention concerne une fibre optique comprenant : un noyau à base de silice ayant un premier indice de réfraction ni ; et au moins une gaine à base de silice entourant le noyau, la au moins une gaine à base de silice comprenant des vides non périodiques diminuant l'indice contenant un gaz, au moins 80 % desdits vides ayant une dimension transversale maximale inférieure à 2 000 nm, et le NA de la couche de fibre située de manière immédiatement adjacente à et à l'intérieur de ladite au moins une gaine à base de silice est d'au moins 0,2.
