Abstract
Cette invention concerne un nouveau procédé et un nouveau dispositif faisant intervenir des moyens à dispersion de longueur d'onde tels qu'un réseau de diffraction pour séparer dans l'espace un signal optique multi-longueur d'onde avec un signal de référence par longueur d'onde en canaux spectraux multiples, et une composante spectrale de référence en un ensemble spectral avec un alignement relatif prédéterminé. Lorsque la composante spectrale de référence est alignée en un point prédéterminé, les canaux spectraux frappent simultanément sur des emplacements désignés tels qu'un ensemble d'éléments récepteurs de faisceau disposé conformément à l'ensemble spectral. La composante spectrale de référence peut en outre être maintenue à l'emplacement prédéterminé via une servocommande, ce qui garantit que les canaux spectraux restent alignés aux emplacements désignés. La présente invention peut être exploitée pour la réalisation d'une nouvelle ligne de systèmes optiques servocommandés, dont des dispositifs de surveillance de puissance spectrale et des multiplexeurs/démultiplexeurs optiques, pour applications à réseaux optiques de multiplexage par répartition en longueur d'onde.
