The results of a theoretical study on collinear acousto-optic (AO) interactions in proton- exchanged lithium niobate (PE:LiNbO3) planar waveguides are presented. The guided-to- leaky mode-conversion for an input optical beam at the wavelength of 623.8 nm by the induced diffraction grating from a collinear surface acoustic wave is analyzed using the coupled-mode theory. Conversion efficiency and AO bandwidth have been calculated as functions of acoustic frequency, interaction length, and acoustic drive power density for different waveguide structures.
