CA 2240519

An optical fibre (1) comprises a core (2) and a cladding (3) that includes an inner cladding region (3a) with a refractive index that is photosensitive to UV light, surrounded by a non-photosensitive outer cladding region (3b). Refractive index gratings can be written into the cladding region (3a). Also, the refractive index of the inner region (3a) can be altered by exposure to UV light to achieve mode matching at a splice between fibres with different core diameters. An optical fibre laser is disclosed with integral refractive index gratings (33, 34, 36) in the cladding of a fibre with an optically active core.

Cette fibre optique (1) comprend une âme (2) ainsi qu'une gaine (3) présentant une région de gaine intérieure (3a), laquelle possède un indice de réfraction photosensible à la lumière ultraviolette et est entourée d'une région de gaine extérieure (3b) non photosensible. Des sélecteurs de mode à indice de réfraction peuvent être inscrits dans la région de gaine (3a). De même, on peut modifier l'indice de réfraction de la région intérieure (3a) par exposition à la lumière ultraviolette, afin d'obtenir une correspondance de mode au niveau d'un raccord entre fibres présentant des diamètres d'âme différents. On décrit un laser à fibre optique possédant des sélecteurs de mode (33, 34, 36) à indice de réfraction, solidaires de la gaine d'une fibre possédant une âme optiquement active.
