Abstract

We present an optical digital processor system containing an array of processing elements. Each processing element is capable of executing arithmetic, logic and interconnect operations. To provide fast execution speed, we use the lookup-table approach. Results of operations are precalculated and stored in truth tables. To record a set of lookup-tables, a modified dual-rail spatial encoding method is used. The truth-tables are recorded in a novel holographic content-addressable memory. To implement a large number of processing elements, a spatially multiplexed hologram was used.
