Abstract

Multiple coherent effects including Fano resonances are observed in self-assembled reduced symmetry gold nanorod systems, in particular Dolmen configurations. The bottom-up chemical method provides high quality units and assemblies (single crystal with low surface roughness and sub 5 nm gaps) that reduce radiative losses from the plasmonic structures. Multiple dark and bright plasmonic resonances are observed in optical dark-field scattering measurements and electron energy loss spectroscopy. These high fidelity structures and narrow resonances are promising for future design of high figure of merit sensors, ultrafast switches and slow light devices for optical information processing.
