Paper Abstract

Chaotic optical signals may be generated by using an acousto-optic system in the Raman-Nath mode. The bistability in the Raman-Nath mode is realized by detecting the intensity of the diffracted optical beams and feeding back the electronic signal to drive the acousto-optic cell. If the parameters of the system are chosen ”judiciously”, the intensity of the output beams oscillates in a chaotic manner in time. The conditions for generating chaos from various diffraction orders of the Raman-Nath cell are derived by calculating the Lyapunov exponents. If the Lyapunov exponent is a positive number then the system generates chaos; otherwise the system remains stable and produces a well-defined output signal. When the Lyapunov exponent for a RamanNath diffraction order is known the physical parameters are calculated so that chaos is produced in the output of the system in that diffraction order.
