A reconfigurable optical device for wavelength-division multiplexing networks, comprising two waveguides (A, B) parallel to each other, with two-dimensional confinement, coupled by a bi-directional coupler (C), suitable to selectively drop one and only one of the channels composing the Wavelength-Division multiplexing signal (WDM); the device is reconfigurable as, by appropriately varying the wavelength of the combined pumping beam inside a first waveguide (A), any channel forming the WDM signal can be dropped.

L'invention concerne un dispositif optique reconfigurable destiné à des réseaux de multiplexage par répartition en longueur d'onde, comportant deux guides d'onde (A, B) parallèles avec confinement bidimensionnel, couplés par un coupleur bidirectionnel (C). Le dispositif selon l'invention permet de dériver sélectivement un des canaux composant le signal de multiplexage par répartition en longueur d'onde (WDM). Par ailleurs, ledit dispositif peut être reconfiguré dans la mesure où chaque canal composant le signal WDM peut être dérivé par modification adéquate de la longueur d'onde du faisceau de pompage combiné dans un premier guide d'onde (A).
