Abstract

An optical content-addressable processor called the multiwavelength optical content-addressable parallel processor (MW-OCAPP) is presented. It harnesses a unique method of wavelength multiplexing and polarization multiplexing to achieve a high level of parallelism. Optical implementation is made possible by exploitation of the noninteractive behavior of coincident light planes of differing wavelengths. This architecture offers database systems constant-time parallel equality and magnitude comparison of multiple comparands with multiple tuples in a relational array.
