An optical module 1 has a planar waveguide 2. The planar waveguide 2 is provided with an optical circuit for an optical switch 3 formed by 2 x 2 cross optical waveguides A1 to D1 and an optical circuit 4 for an optical variable attenuator formed by 2 x 2 cross optical waveguides A2 to D2. Joined onto the planar waveguide is an actuator structure 5 and the actuator structure is constituted by an actuator section 6 for an optical switch and an actuator section 7 for an optical variable attenuator. The optical circuit 3 of the planar waveguide 2 and the actuator section 6 constitute an optical switch 8 , whereas the optical circuit 4 of the planar waveguide 2 and the actuator section 7 constitute an optical variable attenuator 9.

Cette invention concerne un module (1) optique comprenant un guide d'ondes plat (2). Un circuit optique (3) pour un commutateur optique formé par des guides d'ondes optiques A¿1? à D¿1? croisés 2 x 2 et un circuit optique (4) pour un atténuateur réglable optique formé par des guides d'ondes optiques A¿2? à D¿2? croisés 2 x 2 sont disposés sur ce guide d'ondes plat. Une structure de commande (5) est fixée sur le guide d'ondes plat (2). Cette structure de commande (5) comprend une unité (6) de commande pour le commutateur optique et une unité (7) de commande pour l'atténuateur réglable optique. Le circuit optique (3) du guide d'ondes plat (2) et l'unité (6) de commande constituent le commutateur (8) optique alors que le circuit optique (4) du guide d'ondes plat (2) et l'unité (7) de commande constituent l'atténuateur (9) réglable optique.
