Patent

CA 2282423

The present invention relates to a wavelength selective switch. Said switch comprises at least one MMI waveguide, at least one Mach Zehnder waveguide, at least one phase control element and at least one Bragg grating, where said Mach Zehnder waveguide comprises said phase control element and said Bragg grating and is arranged in connection to at least one MMI waveguide. The invention further comprises a method for switching wavelength channels by using the above mentioned wavelength selective switch.

La présente invention concerne un commutateur à sélectivité de longueur d'ondes. Ledit commutateur comprend au moins un guide d'ondes d'interférences multimode (MMI), au moins un guide d'ondes Mach Zehnder, au moins un élément de commande de phase ainsi qu'au moins un réseau de Bragg, dans lequel ledit guide d'ondes Mach Zehnder comprend ledit élément de commande de phase et ledit réseau de Bragg et est agencé en liaison avec au moins un guide d'ondes MMI. L'invention concerne également un procédé de commutation de canaux de longueurs d'ondes utilisant le commutateur à sélectivité de longueurs d'ondes précité.
