B10
Theory of active hyperbolic metamaterials and spaser action in HIOS

Objectives

The development of a comprehensive theoretical framework for the analysis of two prototypical hybrid plasmonic systems is proposed. Specifically, Hyperbolic Metamaterials, i.e., structures consisting of alternating thin layers of plasmonic and dielectric materials, facilitate broad-band enhancements of the optical density of states. In turn, this leads to complex radiation dynamics of embedded active materials. Similarly, the spaser (Surface Plasmon Amplification by Stimulated Emission of Radiation) is a nano-scale generator of coherent plasmons through the interaction of a resonant plasmonic system with the excitations of an optical gain medium.
