Investigation on Expanding the Computing Capacity of Optical Programmable Logic Array Based on Canonical Logic Units

A general structure of an all-optical canonical logic based programmable logic array (CLUs-PLA) based on three methods to expand its computing capacity is presented. These methods include introducing bidirectional structure for nonlinear devices, utilizing wavelength multicast of four-wave mixing (FWM), and exploiting different nonlinear effects simultaneously, which fully utilize the parallelism ...
