Abstract

L'invention concerne un appareil optique passif utilisable comme dé/multiplexeur (MRL) ou routeur en longueur d'onde comprenant un premier et un second réseau de guides d'ondes, respectivement d'entrée et de sortie (I_G ou O_G), une région d'espace libre (RPL) et au moins un troisième réseau de M guides d'ondes, couplés à la même région en espace libre et de différentes longueurs. Selon l'invention, les M guides d'ondes de ce troisième réseau sont sensiblement droits, ou presque droits, et leur axe forme un angle droit avec la seconde surface courbe de définition de cette région en espace libre; les réseaux présentent différentes longueurs pour des intervalles correspondant à des multiples entiers de ΔL/2; chaque guide d'ondes présente un miroir formant un angle droit avec son axe optique.
