Abstract

Un dispositif de multiplexage optique décompose spatialement la lumière collimatée d'un guide d'onde du type fibre optique en bandes de longueurs d'ondes individuelles ou multiplexe de telles bandes de longueurs d'ondes individuelles pour les fournir à un guide d'ondes commun, du type fibre optique, ou à un autre dispositif. Le dispositif de multiplexage optique trouve des applications dans des systèmes de télécommunication par fibres optiques à canaux denses utilisant un multiplexage par répartition en longueurs d'ondes, ainsi que pour divers instruments optiques compacts. La lumière à longueurs d'ondes multiples cheminant dans un guide d'ondes du type fibre optique est séparée en de multiples bandes spectrales étroites qui sont dirigées sur des fibres optiques porteuses individuelles ou sur des détecteurs individuels. Un bloc optique (10) présente un port optique pour le passage de la lumière collimatée à longueurs d'ondes multiples en question et de multiples ports mutuellement espacés le long d'une surface à ports multiples du bloc optique. Un filtre d'interférence continu, à épaisseur variable et à cavités multiples s'étend sur la surface à ports multiples du bloc optique, sur les ports multiples précités. A chacun des ports multiples, le filtre d'interférence continu transmet une sous-gamme différente de longueurs d'ondes de la lumière collimatée à longueurs d'ondes multiples passant par le port optique et réfléchit les autres longueurs d'ondes. La lumière multicolore passant dans le bloc optique depuis le port optique est dirigée vers un premier port des ports multiples sur une surface opposée du bloc optique. La sous-gamme de longueurs d'ondes qui est 'dans la bande' d'un tel premier port des ports multiples (44...54) est transmise par ce port vers la partie locale du filtre d'interférence continu à épaisseur variable, et toutes les autres longueurs d'ondes sont réfléchies. La lumière non transmise par le premier port est réfléchie pour venir sur un second port, auquel une seconde bande de longueurs d'ondes (différente) est transmise et le reste de la lumière est à nouveau réfléchi. Les signaux optiques (32) ainsi réfléchis rebondissent en cascade le long du bloc optique du dispositif de multiplexage, en enlevant successivement chaque canal du signal multiplexé. Dans l'opération inverse, les canaux individuels sont combinés dans le bloc optique et transmis par le port optique.
