Abstract: Absrract-A coupled mode formulation is developed for the analysis of acoustooptic diffraction with multiple acoustic waves at different carrier frequencies For the Raman-Nath (thin ultrasonic grating) regime, analytic solutions are obtained for N s i g n a l s In the Bragg (thick ultrasonic grating) limit, analytic solutions are obtained for two independent signals. Truncated series approximations for N small signals are given for both regimes. The theory is applied to the quantitative evaluation of linear and nonlinear effects occurring in acoustooptic spectrum analysis, optical information processing, multichannel recording, and multiple beam deflection and modulation. These include diffraction efficiency, compression, cross modulation, and spurious intermodulation intensities. The results show that all nonlinear effects considered are substantially reduced in the Brag limit. This is supported by experimental measurements of the various effects, in good agreement with the Bragg limit theory.

- 01 Jul 1984
TL;DR: Two-dimensional optical processing architectures that are implemented with one-dimensional input spatial light modulators are reviewed and the most powerful and versatile optical processors of this type are discussed.
Multichannel acousto-optic crossbar switch.
TL;DR: An optimum switch design based on Fourier optics is developed: a Fourier transform lens is used both to scale the output beams for efficient coupling to the output ports and to provide a necessary optical fan-in from input to output ports.

Multifrequency Acousto-Optic Diffraction in Wideband Bragg Cells
I.C. Chang,Robert T. Weverka +1 more
- 01 Jan 1983
TL;DR: In this paper, a coupled mode analysis for the nonlinear interaction of multiple acoustic waves at different c arrier frequencies is presented for wideband Bragg cells and the dominant contribution of the IMPS is due to acoustic nonlinearities in the Bragg cell medium.

Acousto-optic multifrequency modulators: reduction of the phase-grating, intermodulation products.
TL;DR: It is shown here that a suitable anisotropic interaction can greatly reduce this undesirable effect of the multifrequency acousto-optic modulator efficiency, limited mainly by the two-tone, third-order intermodulation products.
