Abstract

We propose a plasmonic refractive index-sensitive nanosensor based on the electromagnetically induced transparency (EIT) of waveguide resonator systems. The structure consists of one tooth-shaped cavity as well as the bus and stub metal-insulator-metal waveguides. By adjusting the structural geometry, it is demonstrated that the controllable transmission of EIT response can be obtained with the finite-difference-time-domain simulations. It is found that the transmission spectra dip can be strongly controlled by changing the refractive index filled in the stub waveguide. The calculated results show that the sensitivity of the plasmonic nanosensor is 733 nm/RIU.
