Set-valued logic networks based on optical wavelength multiplexing

A set-valued logic network that uses multiwavelength optical circuits to attack the interconnection problems characteristic of highly parallel computing architectures is presented. The basic concept is logic-value multiplexing, which means the simultaneous transmission of logic values represented by optical wavelengths through a waveguide. This concept allows simultaneous execution of several binary operations in a single module to be realized. The systematic design of the set-valued logic network is presented, and it is applied to the sorting network to demonstrate its potential for reducing interconnection complexity.<>
