Abstract

L'invention concerne l'optique des ondes guidées, en particulier la conversion sélective spectrale accordable de modes de rayonnement de guides d'ondes au moyen de matériaux à cristaux liquides. Le principe de fonctionnement est similaire à celui des fibres optiques à réseau de Bragg. L'invention concerne également un dispositif comprenant un guide d'ondes pourvu d'un noyau et d'une gaine, une partie de cette gaine étant constituée de cristaux liquides et disposée entre des électrodes. Le mode d'ondes guidées interfère sur des modifications périodiques d'indice de réfraction le long de l'axe du guide d'ondes, ces modifications étant obtenues par l'utilisation d'un cristal liquide chiral présentant une symétrie de spirale, l'axe de la spirale étant orienté le long de l'axe du guide d'ondes. La gamme spectrale de transformation de modes est définie par un pas de la spirale de cristal liquide chiral, ce pas étant modifié lorsqu'un champ extérieur est appliqué. L'invention permet une réflexion spectrale sélective du mode d'ondes guidées, avec une fréquence centrale accordable de la gamme spectrale de réflexion. La gamme accordable pour une longueur d'onde de 1,5 mkm est supérieure à 200 nm. La présente invention peut être utilisée dans le multiplexage/démultiplexage accordable dans des systèmes de communication par fibres optiques par répartition en longueur d'onde.
