Summary: In this paper, a robust and high performance plasmonic refractive index (RI) sensor based on graphene plasmon waveguide coupled to graphene nano-ring resonator is presented. The characteristics of the RI sensor, including resonance wavelength, wavelength sensitivity, and figure of merit (FoM), are analytically derived. The study demonstrates the possibility of achieving a high FoM through the structural symmetry of the resonator and the tunable physical properties of graphene. Based on numerical solutions, the RI sensor exhibits robust and high performance, making it a promising candidate for practical nanoscale integrated sensors.

Summary: This study demonstrates the feasibility of using a machine learning technique to select the optimal surface plasmonic resonance (SPR) sensor based on specific structural parameters. The particle swarm optimization (PSO) algorithm and a trained ML model are utilized to design a tunable SPR sensor with desired sensing performance. By using a learned ML model to forecast sensor performance, the PSO algorithm can optimize solutions faster, with a speed improvement of four orders of magnitude. The implementation of this composite algorithm enables the rapid and precise creation of an SPR sensor with a sensitivity of 68.754 degrees/RIU and an impressive figure of merit of 100. It is anticipated that this effective and precise method will contribute to the future development of plasmonic devices.
