Electro-Optic Hybrid Logic Gate Derived from a Silicon-Based Hybrid Surface Plasmon Polariton Waveguide

Abstract

Electro-optic hybrid computing is a key research topic in high-performance computing. AND, OR and NON are the most basic computing units. Logic units, which are composed of a Mach Zehnder interferometer (MZI) and a micro ring resonator (MRR), have the issues of large size and poor thermal stability. To solve these problems, this paper discusses the design of AND, OR and NON basic logic units in compact electro-optic logics based on the principle of silicon-based hybrid surface plasmon polariton waveguides. By optimizing the parameters with the Finite Difference-Time Domain (FDTD), the simulation results show that the maximum insertion loss (IL) of the AND, OR and NON logic units is 5.1 dB, and the extinction ratio (ER) is at least 14.3 dB. The experimental simulation results provide a theoretical basis for the design of an electro-optic logic gate derived from a silicon-based hybrid surface plasmon polariton waveguide.
