- 43 - OPTICAL LOGIC ARRANGEMENT Abstract An arrangement for performing an optical logic operation. The optical logic arrangement comprises a plurality of reflection holograms positioned in a two- dimensional array for optically interconnecting a similar plurality of optically nonlinear optical devices also positioned in a two-dimensional array. Each 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 gain function of at least one control light beam applied to the device. Accordingly, each device can regenerate light beams and perform an optical logic function. In response to an output light beam from a specified optical logic element, the associated reflection hologram originates an individual control light beam to one or more designated optical logic elements in the logic array. Consequently, the optical logic elements may be optically interconnected to perform any combination or sequential and combinational logic operations including those, for example, of an optical digital processor.
