Abstract

L'invention se rapporte à un guide d'ondes optique (10), tel qu'une fibre optique, comportant une gaine (12) et une âme (14) et présentant un renflement (16) de la dimension externe sur une longueur préétablie L du guide d'ondes (10). La gaine peut également comporter une couche tampon extérieure (18). Le renflement (16) constitue un moyen à haute résistance et faible fluage pour fixer la fibre (10) à une structure, par exemple un capteur optique. Cette fibre (10) dotée d'un renflement (16) présente un faible facteur de perte de flux de la lumière se propageant dans l'âme (14) à travers le renflement, ainsi qu'une bonne résistance mécanique.
