Sorting is central to the solution of many knowledge-based and switching problems in advance computation and communication systems. Parallel-pipelined sorting algorithms are appropriate for applications that demand high throughput, low delay, and many data channels. One such algorithm, the bitonic sor, can be implemented with passive perfect shuffle interconnects between active stages of compare-and-exchange elements. This paper focuses on optical hardware to implement the CandE operation and show that by taking advantage of a distinctive feature of optical logic, namely bistability, comparison circuits of remarkable simplicity are attainable. Described are implementations of CandE in a Variety of optical device technologies capable of performing latching and nonlatching logic. Based on the device characteristics potential application areas for each technology are outlined.
