New simple acousto-optic (AO) methods of determination of guided-mode propagation constants in planar waveguides are considered. Some promising advantages are shown of the AO methods in the cases of anisotropic waveguides. Experimental verifications of YX-LiNbO3 Ti-diffused single-mode waveguides have been obtained.
