Description

technical field [0001] The invention belongs to the technical field of all-optical comparators and encoders, and in particular relates to a device for simultaneously realizing all-optical comparators and encoders based on SOA nonlinear effects. Background technique [0002] High-speed digital processing can meet the demand for rapid development of data communication in future optical networks. Photonic signal processing in the optical layer helps to perform various computational functions such as packet buffering, bit length conversion, header processing, switching, retiming, shaping, pattern matching and overcoming of all speed electronic limitations. Optical computing offers the possibility of ultra-high-speed and ultra-wideband information processing. An integrated all-optical logic comparator is one of the essential core components in an optical computing system. An all-optical photonic digital circuit capable of comparing two Boolean numbers requires switch control an...
