Plasmonic sensor realized on metal-insulator-metal waveguide configuration for refractive index detection

In this work, a plasmonic sensor established on metal-insulator-metal waveguide configuration is proposed and numerically investigated for biosensing applications. The spectral sensing characteristics of the device are examined via two-dimensional finite element method. Sensitivity (Sbulk) figure merit (FOM) two important parameters that considered to determine performance. Sbulk as ratio between change in resonance wavelength ambient refractive index. Whereas FOM full width at half maximum. offered by ~825.7 nm/RIU ~13.14, respectively. This work can provide guideline realization highly sensitive devices. Full Text: PDF ReferencesN.L.
