摘要：

The proposed all-optical circuit utilizes the deep sub-wavelength confinement properties of plasmonic metal–insulator–metal waveguides. All-optical priority encoder accepts 2 n inputs and produces n outputs. The priority encoder is designed using the plasmonics waveguide-based Mach–Zehnder interferometer (P-MZI). The P-MZI works as an all-optical switch. The switching of the signal depends on the power of the applied optical input signal. This waveguide has a nonlinear material inside. The proposed work is analyzed using the finite-difference time-domain method, and a mathematical description is also given. Parameters such as insertion loss and extinction ratio are reported as 15.82 dB and 0.57 dB, respectively. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
