In this work, all-optical plasmonic NOT logic gate was proposed by using metal-insulator-metal (MIM) plasmonic waveguides design. This logic gate is numerically analyzed by COMSOL Multiphysics 5.3a. Recently, plasmonics have attracted more attention due to its huge applications in all optical signal processing. Due to it’s highly localization to metallic surfaces, surface plasmon (SP) may have many applications in sub wavelength to guide the optical signal in waveguides to overcome the diffraction limit which considered a big problem in conventional optics. The proposed design of MIM structure is consist of a dielectric waveguides plus metallic claddings, which guide the incident light strongly in the insulator region. Strong localization and relatively simple fabrication make the MIM waveguides the potential key design of Nano-scale all optical devices. Our design consists of symmetric ring structures with straight waveguides which based on MIM structure. All-optical logic gate (NOT gate) behavior is achieved from utilizing the interface between straight waveguides and ring structure waveguides. By switching the activation of the control port, the propagation of the outgoing field in the output waveguide will be changed. As the simulation results show, the proposed structure could operate as an all-optical NOT logic gate. This gate would be a potential component in many applications of all-optical signals processing.

In this paper, metal-insulator-metal (MIM) plasmonic waveguide structures and a rectangular cavity resonator at a central frequency of 1550 nm were used to propose a complete full adder. Under this circumstances, the system has a fast function with slight variations in real- time or near real-time manner, and this led to its minimum power consumption, while serving in various situations. In this full adder, we benefited from the property of combining resonant waves in the first and second modes, and we managed to obtain a high transmission coefficient in states where the output must be active. This complete full adder operates through designing 4-input AND, XOR, OR, and NOT logic gates, resulting in the design of a complete full adder with low manufacturing complexity and cost relative to ones designed through combining the conventional 2-input AND and OR gates. In comparison of three computational methods, finite‐difference time‐domain (FDTD) is a simple and versatile method. This method directly discretizes the time‐domain partial differential form of Maxwell's equations in various dimensions while using analytical solution in the remaining direction and solving the 3D scattering problem. Therefore, necessary simulations were conducted using FDTD software, and showed a good fit to the results predicted through approximations intended for theoretical relations.

We propose, analyze, and simulate a configuration to realize all-optical logic gates based on nanoring insulator-metal-insulator (IMI) plasmonic waveguides. The proposed plasmonic logic gates are numerically analyzed by finite element method. The analyzed gates are NOT, OR, AND, NOR, NAND, XOR, and XNOR. The operation principle of these gates is based on the constructive and destructive interferences between the input signal(s) and the control signal. The suggested value of transmission threshold between logic 0 and logic 1 states is 0.25. The suggested value of the transmission threshold achieves all seven plasmonic logic gates in one structure. We use the same structure with the same dimensions at 1550-nm wavelength for all proposed plasmonic logic gates. Although we realize seven gates, in some cases, the transmission of the proposed plasmonic logic gates exceeds 100%, for example, in OR gate (175%), in NAND gate (112.3%), and in XNOR gate (175%). As a result, the transmission threshold value measures the performance of the proposed plasmonic logic gates. Furthermore, the proposed structure is designed with a very small area (400 nm × 400 nm). The proposed all-optical logic gates structure significantly contributes to the photonic integrated circuits construction and all-optical signal processing nanocircuits. , many all-optical plasmonic structures provided nanoscale logic gates.
