Abstract

Optical metamaterials require the manufacture of periodically repeating motives at length-scales that are smaller than the wavelengths they are intended to manipulate. For visible light, this entails the fabrication of 3D design materials with sub-100 nm periodicities. Since this is difficult to achieve using top-down methodologies, bottom-up self-assembly is an interesting alternative approach. The perhaps simplest implementation of self-assembly for metamaterials is the use of block-copolymers replicated into a plasmonic metal.
