The acousto-optic interaction with leaky surface acoustic wave radiation into the bulk of YX-cut LiTaO3 crystals has been investigated. The light incidence and diffraction angles corresponding to the strongest acousto-optic interaction were calculated and measured as functions of the acoustic wave frequency. The dependencies of the diffracted light intensity on the amplitude of radio-frequency voltage applied to the interdigital transducer (IDT) were studied. Our acousto-optic measurements revealed generation, by the IDTs, of slow shear bulk acoustic waves propagating at different angles depending on their frequency. A secondary acousto-optic interaction from the bulk waves radiated by the receiving IDT has been studied.
► Acousto-optic measurements revealed generation of bulk acoustic waves by IDTs.
► Diffraction efficiency depends on acoustic and optical interaction length.
► Re-emission of bulk acoustic waves causes a secondary acousto-optic interaction.
