Abstract

Des longueurs d'onde de filtres optiques de deux AWG (14; 22) montés en série et connectés par un câble de fibres de verre (20), peuvent être ajustées entre elles par détection d'une courbe d'amortissement d'un canal de longueurs d'onde prédéterminé (18-n) d'un premier AWG (14), via une connexion prédéterminée (54-n) du premier AWG (14), le câble de fibres de verre de liaison (20) et une connexion prédéterminée (54-n) du second AWG (22), ladite connexion prédéterminée (54-n) du second AWG (22) étant fermée par une fibre de verre de mesure (56). Une température du premier AWG (14) peut être ajustée, en fonction de la courbe d'amortissement détectée, de telle façon que les longueurs d'onde du filtre (λn) des deux AWG coïncident au moins approximativement.
