Description/Abstract

Metallic nanoscale voids can support both localized and propagating plasmons and form plasmonic crystals. However, constructing 1D arrays is crucial for producing plasmonic circuits. In this paper we report the first experimental evidence of plasmons in templated linear arrays of self-assembled structures. Single and multilayer arrays of gold voids have been fabricated by self-assembly of sub-micron polystyrene spheres in V-shaped trenches in silicon, followed by selective area electrodeposition. Angle-dependent dispersion characteristics reveal the existence of localized plasmons.
