Part I: Mark Stockman
Materials for Nanoplasmonics and Their Fundamental Properties

The materials for nanoplasmonics include metals, in particular, alkaline, alkaline earth and transition metals (including noble metals such as silver, gold and platinum), semi-metals such as graphene, semiconductors (highly doped semiconductors used as plasmonic metals or lightly doped semiconductors used as gain media), topological insulators (whose surfaces can exhibit plasmonic properties) and dielectrics. This part of the tutorial dealt with fundamental properties of the materials. We concentrated on dispersion properties of the plasmonic materials defined by the fundamental principle of causality. We also compared metals with conducting semiconductors and graphene. Novel two-dimensional semiconductors such as transitional metal dichalcogenides were also discussed.

Part II: Mark Stockman
Spaser as Coherent Generator of Nanoplasmonic Fields and Light

In this part of the tutorial, we concentrated on spasers and spaser-based lasers. A spaser is a plasmonic nanosystem containing a metal nanoparticle, which plays a role of the plasmonic resonator, and semiconductor gain shell. We considered fundamental theory of the spaser, including both stationary (CW) operation and its ultrafast kinetics. We reviewed an extensive literature on various spasers demonstrated experimentally and outlined fundamentals of applications of both nanospasers and lasing spasers.

Part III: Mark Luitzen Brongersma
From Metamaterials to Active Metadevices

In this part of the tutorial, an intuitive introduction to the optical properties of metamaterials was provided. Brongersma discussed the possibility of creating two-dimensional (2D) metamaterials from optically resonant nanoscale semiconductor and metallic building blocks. The resulting metafilms and metasurfaces are ideal building blocks for optoelectronic devices that are commonly constructed from layered metal and semiconductor films.
