The deflection of optical guided waves by acoustic waves in layered media is studied. The electric fields that arise in this scattering process lead to complex radiated power distributions. In particular, it is shown that field effects can influence coupling efficiency and beamwidth and that these effects must be included in any description of acoustic-optic light deflection from optical waveguides.
