An article comprising an optical fibre, the fibre comprising at least one core surrounded by a first outer cladding region, the first outer cladding region being surrounded by a second outer cladding region, the first outer cladding region in the cross-section comprising a number of first outer cladding features having a lower refractive index than any material surrounding the first outer cladding features, wherein for a plurality of said first outer cladding features, the minimum distance between two nearest neighbouring first outer cladding features is smaller than 1.0 µm or smaller than an optical wavelength of light guided through the fibre when in use; a method of its production, and use thereof.
L'invention concerne un article qui comprend une fibre optique présentant au moins une âme entourée d'une première région de gainage extérieur, laquelle est entourée d'une seconde région de gainage extérieur. La première région de gainage extérieur comprend, dans la section transversale, plusieurs premiers éléments de gainage extérieur présentant un indice de réfraction inférieur à celui d'un quelconque matériau entourant les premiers éléments de gainage extérieur. Pour plusieurs desdits premiers éléments de gainage extérieur, la distance minimale entre deux premiers éléments de gainage extérieur les plus proches est inférieure à 1,0 µm ou inférieure à une longueur d'onde optique d'une lumière guidée à travers la fibre, pendant l'utilisation. L'invention concerne en outre un procédé de production et d'utilisation de la fibre optique.
