Abstract
An arrangement for performing an optical logic operation. The optical logic arrangement comprises a plurality (100) of reflection holograms (101-109) positioned in a two-dimensional array for optically interconnecting a similar plurality (120) of optically nonlinear self electro-optic effect devices (121-129) also positioned in a two-dimensional array. Each self electro-optic effect device is responsive to control light beams received on either side of the device array for emitting an output light beam that is a nonlinear function of the control light beams. Accordingly, each self electro-optic effect device can regenerate light beams and perform an optical logic function. In response to an output light beam from a specified self electro-optic effect logic element, the associated reflection hologram originates an individual control light beam to one or more designated self electro-optic effect logic elements in the logic array. Consequently, the self electro-optic effect logic elements may be optically interconnected to perform a combination of sequential and combinational logic operations including those, for example, of an optical digital processor.
