Abstract

Experimental investigations of generations and processing of optical patterns in a nonlinear optoelectronic circuits composed of an electronically addressed spatial light modulator and a CCD camera are described. The circuits generates rolls and hexagons, whose pitch has the square root dependence of the spatial frequency upon the positive and negative diffraction length. In compared with a nonlinear optical circuits composed of optically addressed spatial light modulator, the nonlinear optoelectronic circuits have the wide range control of nonlinearity and temporal property, less constraints in an optical and electrical mappings, and a low light level derived from high sensitivity of the CCD camera. We also demonstrate the synchronization of the generated patterns using the optoelectronic circuits with the electronically simulated point nonlinearity and nonlinear mapping.
