Abstract

L'invention concerne un procédé de formation de réseaux de diffraction de guide d'ondes optiques, tels que des réseaux de fibres optiques. Les réseaux sont formés optiquement, un masque de phase étant balayé par un faisceau laser d'exploration afin de générer la configuration des réseaux. Le guide d'ondes et le masque de phase se déplacent l'un par rapport à l'autre au cours du processus d'exploration, faisant varier les caractéristiques du réseau sur sa longueur. Un déplacement relatif dans une direction unique crée une modification du pas du réseau, qui peut être ainsi utilisé pour fabriquer des réseaux modulés en fréquence ou à plusieurs longueurs d'ondes. Un signal de vibration bidirectionnel modifie la robustesse du réseau, qui peut être ainsi utilisé pour fabriquer des réseaux apodisés.
