ABSTRACT:
In accordance with the present invention, an optical processing device and method are provided for processing with extremely low energy requirements. Spontaneous emissions from an excited optical gain medium generate a waveform that propagates within a cavity defined by the gain medium and a reflective device. A first spatial modulating element is disposed in the cavity in the path of the generated wavefront to impose a first spatial pattern thereon. A second spatial modulating element also is disposed in the cavity and imposes a second spatial pattern on the perturbed wavefront carrying the first pattern. When the first and second imposed spatial patterns have dual spatial pattterns, light is directed back along pathways through the cavity to induce stimulated emission and eventually resonance in the cavity.
