An optical switch includes at least one input port for receiving a WDM optical signal having a plurality of wavelength components, at least three output ports, and a plurality of wavelength selective elements each selecting one of the wavelength components from among the plurality of wavelength components. A plurality of optical elements are also provided, each of which are associated with one of the wavelength selective elements. Each of the optical elements direct the selected wavelength component that is selected by its associated selected element to a given one of the output ports independently of every other wavelength component. The given output port is variably selectable from among all the output ports.

L'invention concerne un commutateur optique comprenant au moins un port d'entrée destiné à recevoir un signal optique de multiplexage par répartition en longueur d'ondes constitué de plusieurs composantes de longueur d'ondes, au moins trois ports de sortie, et plusieurs éléments sélecteurs de longueur d'ondes, chacun permettant de sélectionner une des composantes de longueur d'ondes. Le commutateur comprend aussi des éléments optiques dont chacun est associé à un des éléments sélecteurs de longueur d'ondes. Chacun de ces éléments optiques dirige la composante de longueur d'ondes sélectionnée par son élément associé vers l'un des ports de sortie de manière indépendante par rapport à chaque autre composante de longueur d'ondes. Le port de sortie donné peut être choisi de manière variable parmi tous les ports de sortie.
