Abstract

Selon l'invention, une antenne réseau à commande de phase optique (5) est couplée à un support de transmission (8) et est ajustée en continu, par ex. par modification de la température, de sorte à pouvoir déterminer, avec les courbes de filtrage de l'antenne réseau à commande de phase, les longueurs d'ondes de signaux sur la base d'une comparaison entre les variations des puissances optiques des signaux dans les guides d'ondes (60) situés côté sortie. Deux guides d'ondes du même canal, situés côté sortie, sont couplés en un angle différant de zéro (porte double), de manière à obtenir une longueur d'ondes de référence pour étalonner l'antenne réseau à commande de phase, sur la base des différentes propriétés de transmission.
