The application of SPP has created possibilities for the size of photonics devices compared to the operating wavelength. However, SPP has severe Ohmic attenuation and significant optical insertion loss, resulting in limited optical signal transmission distance. To eliminate the above situation, we used a silicon waveguide with hybrid mode SPP, and provide relevant theoretical and analysis. Hybrid SPP silicon waveguides, and then provide design methods for electro-optic hybrid half adders, full adders, subtractors, and multiplications based on SPP, and provide detailed discussions and...
