“…The operation wavelength of 1,550 nm was chosen for use in our proposed system due to its numerous applications in optical communications. The effective refractive index and structural characteristics of the material dictate the resonance wavelengths of plasmonic systems [25]. The proposed gates are evaluated by considering the transmitted optical power as a function of incident wavelength, and the contrast ratio (CR) between the (ON and OFF) states.…”

In this paper, we report new nanoscale plasmonic multiple inputs logic gates based on insulator-metal-insulator (IMI) nanoring waveguides. The proposed all-optical gates are numerically analyzed by the finite element method. NOT, AND, NAND, NOR, and EX-NOR all-optical logic gates were suitably designed and investigated based on the linear interface between the propagated waves through the waveguides. The operation wavelength was 1550 nm. The simulation results show that the optical transmission threshold of (0.26) which performs the operation of planned logic gates is accomplished. Moreover, simulation results show that our compact structure of all-optical logic gates may have potential applications in all-optical integrated networks.

“…49 A similar attempt was made recently with further reduced dimensions of using metal insulator metal (MIM) plasmonic waveguides and improved the CR value by 27.8 dB. 50 A simpler design for AO-AND gate was attempted using a Y-shaped MIM plasmonic waveguide with improved flexibility and operating speed. 51 The diffraction limit is a factor that brings down the photonics-based design approach when attempting compact designs with device dimensions comparable to operating wavelength.…”

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.

“…The IL and ER of our work are found to be 0.165 dB and 14.11 dB respectively. For better performance of logic gates, the insertion loss should be low and the Extinction ratio should be high as possible [44]. This paper work is compared with the previously published works in following parameters as shown in the Table . 7.…”

All-optical logic gates have proven their significance in the digital world using which all high-speed computations are calculated. In this paper, we have proposed a novel structure for all-optical AND using the concept of power combiner using Y-shaped metal-insulator-metal waveguide under the footprints of 4 µ𝑚 × 7 µ𝑚. This design works under the principle of linear interference. The insertion loss and extinction ratio of the design are given by 0.165 dB and 14.11 dB, respectively. The analysis of the design is carried out by finite-difference-time-domain (FDTD) method and verified using MATLAB. This minimized structure can be used to design any complex logic circuits to achieve better performance in future.
