Patent

CA 2129778

The device includes a first and a second optical circulator having an input portand an output port that are the inputs and the outputs of the switch, as well as an optical bandpass filter placed between the two circulators and connected with means for switching its state so that the filter either reflects or transmits a given wavelength, thus allowing a carrier with this wavelength at the input port of one of the circulators to reach the output port of the samecirculator or the output port of the other circulator.

e dispositif comprend un premier et un deuxième circulateurs ayant une entrée et une sortie qui sont les entrées et les sorties du commutateur, ainsi qu'un filtre passe-bande optique placé entre les deux circulateurs et connecté avec des moyens de commuter son état pour que le filtre réfléchisse ou émette une longueur d'onde donnée, ce qui permet à une porteuse ayant cette longueur d'onde à l'entrée d'un des circulateurs d'atteindre la sortie du même circulateur ou la sortie de l'autre circulateur.
