We report plasmonic Fabry-Perot nano-cavities formed by high aspect ratio metal mirrors on a metal surface. Quality factors from 100-200 were obtained, limited by plasmonic losses and fin scattering at short and long wavelengths respectively.
The interaction between surface plasmons and optical emitters is fundamentally important for engineering applications, especially surface plasmon amplification and controlled spontaneous emission. We investigate these phenomena in an active planar metal-film system comprising InGaN/GaN quantum wells and a silver film. First, we present a detailed study of the propagation and amplification of surface...
Summary form only given. There is considerable interest in the study of light emission from optical cavities whose dimensions are of the order of a wavelength in all three dimensions. Most work has been carried out on etched structures. We propose and demonstrate a novel method for the fabrication of GaAs semiconductor optical microstructures by self-organization during molecular beam epitaxial growth...
