We consider some principles of the binary encoded digital modulation of light based on exploiting collinear three-wave coupled states. The analytical model of shaping acousto-optical three-wave weakly coupled states is presented. The analysis developed is tested experimentally using the collinear Bragg regime of acousto-optical interaction in uniaxial single crystal. The experiments carried out make it possible to observe the dynamics of reshaping acousto-optic three-wave weakly coupled states under variations in the acoustic pulse width and the frequency mismatch. Applying the technique of localizing the coupled states to the problem of binary modulation of light beam, the conversion of multi-bit electronic signals into binary encoded optical pulse trains is demonstrated.
