Design of optical circuits for multiplex computing based on set-valued logic

A new computer architecture that uses multiwavelength optoelectronic integrated circuits is proposed that addresses problems caused by interconnection complexity. Multiwavelength-optoelectronicintegrated-circuit architectures, in which various wavelengths are employed as information carriers, provide the wavelength as an extra dimension of freedom for parallel processing; thus we can perform several independent computations in parallel in a single optical module. This multiplex computing enables us to reduce the number of interconnections on the chip and to improve interconnection complexity. The systematic synthesis of the optical circuits for multiplex computing is discussed on the basis of a set-valued switching algebra.
