Abstract[English]
According to an aspect of the present disclosure an optical switch device is provided. The optical switch device comprises a waveguide structure and a plurality of electrodes. The waveguide structure comprises a plurality of primary optical waveguides, each primary optical waveguide connecting a respective optical input and a respective optical output, and a set of one or more chargeable optical waveguides electrically isolated from the plurality of primary optical waveguides. The plurality of electrodes is configured to control a charge state of the set of one or more chargeable optical waveguides. The waveguide structure is configured to optically couple an optical signal received at a first optical input to a first optical output or a second optical output based on the charge state of the set of chargeable optical waveguides.[French]
Un aspect de la présente divulgation concerne un dispositif de commutation optique. Le dispositif de commutation optique comprend une structure de guide d'ondes et une pluralité d'électrodes. La structure de guide d'ondes comprend une pluralité de guides d'ondes optiques primaires, chaque guide d'ondes optique primaire reliant une entrée optique respective et une sortie optique respective, et un ensemble d'un ou de plusieurs guides d'ondes optiques chargeables isolés électriquement de la pluralité de guides d'ondes optiques primaires. La pluralité d'électrodes est conçue pour commander un état de charge de l'ensemble d'un ou de plusieurs guides d'ondes optiques chargeables. La structure de guide d'ondes est conçue pour coupler optiquement un signal optique reçu au niveau d'une première entrée optique à une première sortie optique ou à une seconde sortie optique en fonction de l'état de charge de l'ensemble de guides d'ondes optiques chargeables.
