This paper presents wire-free computing circuits using optical wave-casting to provide a solution to the interconnection problems in parallel processing. The 'wave-casting' implies wire-free communication scheme, where intensity-modulated optical signals are employed as information carriers and their frequencies represent the information in the system. In wave-casting-based parallel processing, each processing element broadcasts its output in its unique frequency. The frequencies thus produced are multiplexed in free space, and are selectively received at the specified destination to achieve wire-free communication among the processing elements. This paper discusses the design of wire-free logic circuits based on this principle and its application to a fully parallel visual processing system.
