A novel add/drop optical filter providing arbitrary channel arrangements between two input WDM signals and two output WDM signals is presented. The device consists of two WGR's connected by 2x2 optical switches in each WGR branch. The same circuit can also be used as a 2x2 wavelength-space switch for WDM signals. In both cases N channel arrangements between the two outputs are possible when the two input signals each support N channels.

L'invention est un filtre optique d'insertion-extraction d'un type nouveau qui permet d'établir des configurations de canal quelconques entre deux signaux d'entrée à multiplexage optique et deux signaux de sortie à multiplexage optique. Le dispositif de l'invention est constitué de deux guides de lumière connectés par 2 x 2 commutateurs optiques dans chacun des branchements de guidage. Ce même circuit peut également être utilisé pour commuter 2 x 2 longueurs d'onde de signaux à multiplexage optique. Dans les deux cas, N~ configurations de canaux sont possibles entre les deux sorties quand les deux signaux d'entrée peuvent contenir N canaux chacun.
