Abstract

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