Abstract

L'invention concerne une préforme de fibre optique guide d'ondes et une fibre optique guide d'ondes, étirée à partir de cette dernière, une modification de la densité et donc des indices de réfraction de la couche de gainage (42) étant induite d'une manière présélectionnée, axialement le long de la préforme et de la fibre guide d'ondes associée. La modification axiale de la densité de la couche de gainage (42) est due à la fraction du volume de gainage qui est constituée d'air ou d'un verre dont la composition est différente de celle du verre de la gaine de base. La modification axiale des indices de gainage modifie la répartition de l'énergie monomode, ce qui modifie les paramètres clés relatifs à la fibre guide d'ondes, tels que l'ampleur et le signe de la dispersion, la longueur d'onde de coupure et la longueur d'onde de dispersion zéro. L'invention porte également sur des procédés de fabrication de structures possédant une couche de gainage variable axialement ainsi que sur des préformes, dont des fibres guides d'ondes étirées à partir de ces dernières, qui guident la lumière grâce à la structure cristalline opto-électronique de la longueur totale de la couche de gainage ou de segments de cette dernière.
