Independently tunable triple Fano resonances in plasmonic waveguide structure and its applications for sensing

Abstract: A surface plasmon polaritons (SPPs) waveguide structure composed of a metal-insulator-metal (MIM) waveguide with a ba e, a special square cavity (SSC) and a ring cavity (RC), is proposed to realize independent tuning of triple Fano resonances. Using the nite element method (FEM), the magnetic eld distributions and optical transmission spectra of the structure are analyzed in detail. The simulation results show that the structure achieves triple Fano resonances originated from two different mechanics.One of Fan… Show more

“…The MIM waveguide structures can generate various phenomena, such as Fano resonance and Lorentzian resonance [9,10]. Among them, Fano resonance, resulting from the interference between a continuous state and a discrete state, is an exemplary resonant phenomenon that exhibits a sharp and asymmetrical line profile [9].…”

Among them, Fano resonance, resulting from the interference between a continuous state and a discrete state, is an exemplary resonant phenomenon that exhibits a sharp and asymmetrical line profile [9]. These properties make Fano resonance highly sensitive to variations in structure parameters as well as changes in the refractive index of the surrounding environment [11].…”
