Spectral tunability of a plasmonic antenna with a dielectric nanocrystal: Yury Alaverdyan, Nick Vamivakas, Joshua Barnes, Claire Lebouteiller, Jack Hare, Mete Atatüre
We show that the positioning of a nanometer length scale dielectric object, such as a diamond nanocrystal, in the vicinity of a gold bowtie nanoantenna can be used to tune the plasmonic mode spectrum on the order of a linewidth. We further show that the intrinsic luminescence of gold enhanced in ... [Opt. Express 19, 18175-18181 (2011)]
