Abstract

We propose a novel sensing system using the plasmonic resonator for detecting a minor changes of the refractive index. The detection performance of our device has been numerically evaluated by (FDTD) finitedifference time-domain simulations. Our design can be easily fabricated using the focus ion beam milling technique. It leads to a highly compact sensor in terms with high sensitivity and high detection limit. © 2014 SPIE.
