Abstract

Self-organization of light into a hexagonal spot array and its rotation using photorefractive KNbO₃:Fe is investigated. Furthermore two-beam coupling configurations are employed to obtain the phase conjugate image and edge extraction of an object using photorefractive KNbO₃:Fe. Finally, the self-organization is utilized to broadcast an input object to the location of each of the spots.
