Nonlinear dynamics of Bragg-domain acousto-optic hybrid feedback for first-order scattering of profiled optical beams

A series of recent studies involving hybrid acousto-optic (AO) scattering in the Bragg domain under first-order feedback have shown the ability of the AO feedback system to encrypt, transmit and decrypt RF information applied via the sound driver. The basic premise of this operation is founded on the chaotic nature of the hybrid Bragg cell under feedback [1-3].
