Dual-input hybrid acousto-optic set-reset flip-flop and its nonlinear dynamics

Abstract

The characteristics of a dual-input hybrid acousto-optic device are investigated numerically and experimentally. The device, which operates as a set-reset flip-flop, uses the well-known bistable acousto-optic device with feedback to which two input beams are applied. The resulting flip-flop is analyzed numerically by use of nonlinear dynamical and nonlinear circuit-modeling techniques, and some of its properties are demonstrated experimentally.

Exact solution for four-order acousto-optic Bragg diffraction with arbitrary initial conditions

“…The physical limitations in the usage and accuracy of the four-order analytical solution were discussed in Section 4, and it is believed that most of these restrictions can be removed with future work. In a recent investigation a dual input hybrid AO flip-flop was proposed and its performance analyzed using a strong two-order model for strong AO interaction [14]. Due the element of chaotic oscillation in their calculations, we believe that our four-order quadinput strong interaction solution developed here could be used to refine the analysis by more accurately accounting for the fI −2 ; I þ1 g orders.…”

Isotropic Two-Dimensional Differentiation Based on Dual Dynamic Volume Holograms

“…Through Bragg diffraction, acousto-optic interaction can control the spatial frequency of light signals [12,13]. Compared to digital image processing techniques, using acousto-optic interaction in optical imaging systems can achieve dynamic and real-time programmable laser beam modulation [14][15][16][17]. An acousto-optic modulator (AOM) is considered as a dynamic thick hologram and is a type of spatial light modulator based on acousto-optic interaction [18], which is widely used in the real-time processing of light waves due to its high reliability, fast response speed, and programmability.…”
