Disclosed is an acousto-optic device having a number of acoustic attenuating structures and a method to limit the parasitic effects of a surface acoustic wave. The structures include any combination of the following: surrounding the acousto-optic conversion region with acoustic absorber, placing acoustic absorber near to the transducer(s), placing a strip of acoustic absorber between optical waveguides formed in the device, shaping one or more ends of acoustic waveguides formed in the device to absorb energy from the transducer(s), and/or extending the acoustic waveguides to further limit irradiation of unguided acoustic waves.

L'invention concerne un dispositif acousto-optique présentant un certain nombres de structures d'atténuation acoustiques, et un procédé pour limiter les effets parasites d'une onde de surface acoustique. Ce procédé consiste à entourer la zone de transformation acousto-optique avec un matériau absorbant le son, à placer ce matériau absorbant à proximité du (des) transducteur(s), à placer une bande d'absorbant entre les guides d'ondes optiques formés dans le dispositif, à donner une forme à une ou plusieurs extrémités des guides d'ondes optiques formés dans le dispositif pour absorber l'énergie provenant du (des) transducteur(s) et/ou étendre les guides d'ondes optiques pour limiter encore le rayonnement des ondes acoustiques non guidées.
