Abstract

L~invention concerne un circuit plan d~onde de lumière incluant un filtre optique à deux étages à utiliser dans un transmetteur/récepteur bidirectionnel. Un premier étage comprend un filtre optique non-dispersant qui autorise la lumière d~une certaine plage de longueurs d~onde, en l~occurrence un canal signal d~une source laser, à être projetée sur un guide d~onde d~entrée/sortie, alors que de la lumière d~une autre plage de longueurs d~onde, en l~occurrence un ou plusieurs canaux de détecteur, sera dirigée du guide d~onde d~entrée/sortie vers un deuxième étage. Le deuxième étage comprend un réseau de diffraction réfléchissant ayant une résolution supérieure au premier étage, fournissant une bande passante de 2 à 5 fois plus étroite que le premier étage.
