Abstract

In this paper we present numerical simulations of various plasmonic and silicon-on-insulator (SOI) nanostructures for optical label free biosensors. The results are presented for study of SOI micro wheel resonators and plasmonic gold nano ring, cup and disc arrays. We show that implementation of the sub-wavelength structures into the devices increases the light-matter interaction and the sensitivity of the biosensors. The simulations are performed using finite element method (FEM) and finite-difference-time-domain (FDTD) method.
