We estimate the effective photo-elastic constants peculiar to a two- and three-phonon scattering of light in Bragg regime in optical modulators based on tellurium dioxide crystalline structures. A triplet or quartet of modes appears within the interaction between the incident light beam and the acoustic wave under action of a square-law nonlinearity in similar structures. The analysis and numerical simulations are formulated in terms of the eigen-vectors for light modes in anisotropic medium and take into account the effect of optical activity in TeO2. This analysis is devoted to estimating and comparing the effective photo-elastic constants inherent in normal and anomalous regimes of acousto-optical interaction in tellurium dioxide and oriented to performing the optical modulators. The obtained experimental data on a two- and three-phonon light scattering are discussed in connection with practical estimations.
