Quadruple half adder and half subtractor design using SLM and Savart plate

Abstract

This paper proposes quadruple half adder and half subtractor circuit design using spatial light modulator (SLM) and Savart plate. Over the last 2 decades, advanced technology at high-speed computation has generated large volumes of data. For some novel approaches in data processing techniques to deal with this large number of data, the ultra-high speed data processing system is required. Now optical multiple-valued logic functions are of greatest interest in recent years towards optical logic and information processing system. In order to overcome the electronic bottlenecks and fully exploit the advantages of optics, polarization properties of light realization come from nonlinear optics. It increases the scope of all-optical signals processing in high-speed photonic networks. To this aim, the designs need the use of nonlinear optics capable of controlling multi-valued signals. And to achieve this goal, the polarization properties of light in optical domain are used to the design of quadruple half adder half subtractor circuits.
