Fano resonances in disk-ring plasmonic nanostructure: strong interaction between bright dipolar and dark multipolar mode.

Abstract

This Letter presents a plasmonic nanostructure consisting of a nanodisk and a nanoring. The nanodisk is outside of the nanoring. The quadrupolar, hexapolar, and octupolar resonance modes of the nanoring are excited easily by the bright dipolar mode of nanodisks. This nanostructure shows strong interaction and deep Fano dips. In addition, the resonance… (More)
