Modeling of Hybrid Plasmonic Ring Resonator Based on Dielectric Filled Subwavelength Metal Grating
Source abstract
Abstract
A nanophotonic dual ring Cu-SiO2-Si-Cu-SiO2 plasmonic switch with subwavelength metal grating as switching element is designed and simulated in this paper. The 2D finite element method (FEM)–based COMSOL simulations are performed in the optical C-band to examine its switching performance. Switching is achieved with metal-insulator transition (MIT) phenomenon in VO2 filled subwavelength metal grating (SW-MG), placed in between the two rings of equal radius (R = 1.04 μm). The impact of ring and SW-MG geometrical parameters on the switching performance is also presented. Numerical simulation shows an extinction ratio (ER) of 4.14 dB, along with free spectral range (FSR), figure of merit (Q) of (129 nm, 68.03) and (173 nm, 96.12) in the ON state and OFF state, respectively.
