Abstract

Cette invention se rapporte à un commutateur optique et multiplexeur à insertion-extraction en longueur d'onde, qui utilise un sélecteur de canal (10) pour assurer la sélection du canal et un fonctionnement reconfigurable. Le sélecteur de canal (10) comporte une partie filtre segmenté (100) et un miroir fortement réfléchissant (110). Les sélecteurs de canal (10) peuvent être montés en cascade pour former un système de multiplexage par répartition en longueur d'onde à n longueurs d'onde. Le multiplexeur à insertion-extraction en longueur d'onde permet de sélectionner un canal de longueur d'onde parmi une multitude de canaux, en plaçant le sélecteur de canal approprié (10) dans la trajectoire du faisceau lumineux.
