An optical switch has a plane waveguide provided with optical waveguide, and an actuator structure including a beamlike member supported in a doubly supported manner on the plane waveguide. A mirror for shutting out light passing on the optical waveguide is provided in the central region of the beamlike member. Interconnecting members extending in the longitudinal direction of the beamlike member are coupled to the both ends of the beamlike member. The interconnecting members preliminarily exert a compressive force on the beamlike member so as to deflect the beamlike member with compression stress in an initial state in which the mirror is located at a position where the mirror allows the light passing on the optical waveguide to pass or at a position where the mirror shuts out the light passing on the optical waveguide.
Un commutateur optique comprend un guide d'ondes optique plan et une structure permettant d'actionner l'appareil. Cette structure comporte une poutre fixée au guide d'ondes par deux supports. Un miroir, dont la fonction est d'intercepter la lumière traversant le guide d'ondes, est fixé au centre de la poutre. Des éléments interreliés qui s'étendent dans la direction longitudinale de la poutre sont fixés aux deux extrémités de cette dernière. La principale fonction de ces éléments est d'exercer une force de compression sur la poutre afin de lui imprimer une déformation initiale qui place le miroir dans une position qui permet le passage de la lumière qui traverse le guide d'ondes ou, au contraire, en bloque le passage.
