Manipulating and controlling photons on nanoscale needed for the nanophotonic circuitry and other important applications requires novel plasmonic metamaterials with unique properties. Recent progress in the development of optical metamaterials allows unprecedented control over the flow of light on the nanoscales. Metamaterials (MMs) are rationally designed artificial materials with versatile properties that can be tailored to fit almost any practical need and thus go well beyond what can be obtained with “natural” materials. In this talk, we review the exciting field of optical metamaterials and discuss the recent progress in developing tunable and active MMs, nanolasers, and a new means for engineering the photonic density of states with MMs. Novel plasmonic materials with superior properties based on transparent conducting oxides and ceramics will be outlined. Finally, we consider a new approach for controlling light by using 2D meta-surfaces.
