Abstract :
We have investigated acoustooptic propertied of acoustic and planar thin-film Ta/sub 2/O/sub 5/ waveguides with ZnO surface acoustic wave /SAW/ transducer. We have measured velocity and attenuation of SAW and acoustooptic interaction efficiency as a function of Ta/sub 2/O/sub 5/ waveguide thickness. Measured SAW velocity inTa/sub 2/O/sub 5/ has equaled 2250 m/s. Maximum diffraction efficiency per unit acoustic power and unit transducer aperture has equaled 0.61 %/mW·mm.
