Abstract

Plasmonic structures offer a unique capability to generate electromagnetic oscillation in a tightly confined space at the metal-dielectric interface. This localized intense field can be used to significantly enhance light-matter interaction in an active material. Here, we use a hyperbolic metamaterial resonator on a UV AlGaN multiple quantum well to demonstrate a UV plasmonic nanolaser. The hyperbolic metamaterial consists of metal/dielectric multiple layer structure, which has dielectric permittivity tensor of opposite signs in two orthogonal directions. By proper design, it has an indefinite hyperbolic dispersion. We will discuss the resonator dimension design using this unique hyperbolic dispersion to enhance quantum well radiation for laser operation.
