Abstract

Atomic and Molecular Physics and Optics Electronic Optical and Magnetic Materials Electrical and Electronic Engineering
Plasmonic dark modes of gold nanoantennas are observed in evanescent waves. Dark mode not only has a higher extinction coefficient but also achieves higher sensitivity to the surrounding environment. The sensitivity of the dark mode is 4.84 times that of the bright mode in figure of merit. © 2015 OSA.
