Abstract

Metamaterials are artificial media structured on the sub-wavelength scale. While conventional materials derive their electromagnetic characteristics from the properties of atoms and molecules - metamaterials enable us to design our own 'meta-molecules' and interactions between them and thus access new ground-breaking functionalities.
Metamaterials are expected to have an impact across the entire range of technologies where electromagnetic radiation is used, and provide a flexible platform for modelling and mimicking fundamental physical effects as diverse as superconductivity and cosmology and for templating electromagnetic landscapes to facilitate observations of otherwise difficult to detect phenomena.
We report an overview on our recent results on new phenomena in metamaterials underpinned by meta-molecular interactions. This will include results on light localization in metamaterial arrays, metamaterial "lasing spaser", quantum Purcell enhancement of luminescence and spectral mode collapse.
Furthermore we will introduce a range of novel functionalities observed in nanostructured photonic metamaterials containing nonlinear and active media such as switchable chalcogenide glass, carbon nanotubes, graphene and semiconductor quantum dots.
