We report a development of an electro-optomechanical system based on a surface acoustic wave (SAW), where a piezoelectric material with a large optoelastic susceptibility is used for the coupling of both a radio wave and optical light to the SAW. In the optical domain, we exploit a tensorial nature of the optoelastic effect to show a polarization dependence of the photon-SAW interaction. We discuss the construction of two-dimensional SAW focusing circuits for the coupling enhancement and the optical cavity enhanced photon-phonon scattering. We estimate an optomechanical coupling rate g0 of the system and discuss the future direction for the improvement of the coupling strength.
