“…The validation of the proposed plasmonic NAND logic gate is explained in Table 3. 2, the value of extension ratio of the plasmonic NAND gate is 8.85 dB that is regarded as a medium value and the performance of this gate is Good and efficient according to [12]. While the value of MD is 96.75% (According to Equation 3) that is regarded very high value and the dimensions of the proposed structure are excellent and optimum.…”

“…SPPs are excited when the input port(s) and control port are launched by a plane wave with TM-polarized. The performance of the proposed device is measured by three criteria: the first is the borderline between Logic 0 and Logic 1 at the output that is called transmission, the transmission is defined by Equation 1 [12][13]. Logic 0 and logic 1 are separated by 0.3, which is the transmission threshold value.…”

Though photonics displays an attractive solution to the speed limitation of electronics, decreasing the size of photonic devices is one of the major problems with implementing photonic integrated circuits that are regarded the challenges to produce all-optical computers. Plasmonic can solve these problems, it be a potential solution to fill the gaps in the electronics (large bandwidth and ultra-high speed) and photonics (diffraction limit due to miniaturization size). In this paper, Nano-rings Insulator-Metal-Insulator (IMI) plasmonic waveguides has been used to propose, design, simulate, and perform all-optical universal logic gates (NOR and NAND gates). By using Finite Element Method (FEM), the structure of the proposed plasmonic universal logic gates are designed and numerically simulated by two dimensions (2-D) structure. Silver and Glass materials were chosen to construct proposed structure. The function of the proposed plasmonic NOR and NAND logic gates was achieved by destructive and constructive interferences principle. The performance of the proposed device is measured by three criteria; the transmission, extension ratio, and modulation depth. Numerical simulations show that a transmission threshold (0.3) which allows achieving the proposed plasmonic universal logic gates in one structure at 1550 nm operating wavelength. The properties of this devise was as follows: The transmission exceeds 100% in one state of NAND gate, medium values of Extension Ratio, very high MD values, and very small foot print. In the future, this device will be the access to the nanophotonic integrated circuits and it has regarded fundamental building blocks for all-optical computers.

All-optical logic gates (AO-LGs) are the key elements that play a pivotal role in the development of future all-optical networks and all-optical computing. A complete overview of the seven all-optical logic gates (i.e., AND, OR, NOT, XOR, XNOR, NAND, and NOR) based on their design techniques and applications are covered, including the latest technologies, such as topological photonics and artificial intelligence-based designs techniques. In addition, we have further categorized the AO-LGs as reconfigurable gates, simultaneous gates, reversible gates, modulation-based gates, and data rate-based gates. The techniques to implement these different classes of gates are reviewed and their limitations are discussed. We also discuss in brief the various simulation tools used to design and analyze the AO-LGs. Finally, the most feasible techniques for constructing optical integrated circuits based on the existing fabrication technologies and available resources are explored, and future prospects are outlined.

In this paper, high efficiency multi-functional all-optical logic gates based on a metalinsulator-metal (MIM) plasmonic waveguide structure with Kerr-type nonlinear nano-ring resonators are proposed. The proposed structure consists of three straight input ports, eight nano-ring resonators filled with the Kerr-type nonlinear medium, and one straight output port. By fixing the input signal power and properly changing the control power, it can be used to design high efficiency multi-functional all-optical logic gates. The numerical results show that the proposed Kerr-type nonlinear plasmonic waveguide structures could really function as all-optical XOR/NXOR, AND/NAND, and OR/NOR logic gates in the optical communication spectral region. The transmission efficiency of the high logic state is higher than 95%, and that of the low logic state is about 0% at the wavelength 1310 nm. The performance of the proposed logic gates was analyzed and simulated by the finite element method (FEM).
