Paper Abstract

Spatial and temporal properties of spontaneously pattern generations in an optoelectronic system composed of an electronically addressable spatial light modulator, detector array, and two-dimensional optical feedback are experimentally demonstrated. The square root dependence of the main spatial frequency of the generated pattern on the positive and negative diffraction lengths of the optical feedback under the inversion property of the spatial light modulator is presented. The optoelectronic system has a serial process, but the property of the pattern generation are almost equivalent to them in an all-optical system based on an optically addressed spatial light modulator. The optoelectronic feedback system can function as the simulator of a two-dimensional optical system and the controller for an all-optical system, because it has the wide range of control parameters and high conductivity to an electronic system. We demonstrate the simulation of the optical system including many spatial light modulators and the dynamic control of the optical feedback system.
