Abstract

Here we propose two encoding schemes that utilize both light intensity and polarization to code input data in digital-optical computing. This approach results in a more efficient information carrying and processing technique when compared with the traditional intensity-only or polarization-only encoding schemes. Optical logic units that are based on the proposed encoding schemes are designed. A recursive parallel adder and a carry look-ahead adder that use these logic units as building blocks are also described.
