Abstract
Les réseaux de Bragg sur fibre ont été gravés en fibres à cristaux photoniques de silice pure et en cônes de fibre à cristaux avec un rayonnement infrarouge de 125 fs, 800 nm. De hautes réflectivités ont été atteintes avec un temps d'exposition court dans les cônes de fibre. Les réflexions du réseau en multimode et en mode simple ont été réalisées dans les cônes de fibre. En effilant les fibres à cristaux photoniques, la diffusion a été réduite et la lumière à l'extérieur des fibres a pu atteindre le niveau requis pour graver un réseau.
