The design, analysis, and simulation of an optimized all-optical AND gate using a Y-shaped plasmonic waveguide for high-speed computing devices

All-optical logic gates have proven their significance in the digital world for implementation of high-speed computations. We propose herein a novel structure an all-optical AND gate using concept power combiner based on Y-shaped metal–insulator–metal waveguide with 4 µm × 7 footprint. This design works principle linear interference. The insertion loss and extinction ratio are given as 0.165 14.11 dB, respectively. is analyzed by finite-difference time-domain (FDTD) method verified MATLAB. minimized can be used to any complex circuit achieve better performance future.
