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 inVO2 filledsubwavelengthmetalgrating(SW-MG),placedinbetweenthetworingsofequalradius(R=1.04μm).Theimpact of ring and SW-MG geometrical parameters on the switching performance is also presented. Numerical simulation shows an extinctionratio(ER)of4.14dB,alongwithfreespectralrange(FSR),figureofmerit(Q)of(129nm,68.03)and(173nm,96.12) in the ON state and OFF state, respectively.
