Coherent metamaterials and the lasing spaser
Coherent metamaterials and the lasing spaser
In 2003 Bergman and Stockman introduced the spaser, a quantum amplifier of surface plasmons by stimulated emission of radiation. They argued that, by exploiting a metal/dielectric composite medium, it should be possible to construct a nano-device, where a strong coherent field is built up in a spatial region much smaller than the wavelength. It was suggested that V-shaped metallic inclusions, combined with a collection of semiconductor quantum dots could lead to a realization of the spaser. Here we introduce a further development of the spaser concept. We show that by combining the metamaterial and spaser ideas one can create a planar narrow-diversion coherent source of electromagnetic radiation that is fuelled by plasmonic oscillations. We argue that two-dimensional arrays of a certain class of plasmonic resonators supporting high-Q current excitations belong to a new category of coherent metamaterials that provide an intriguing opportunity to create a spatially and temporally coherent laser source, the Lasing Spaser.

Abstract
In 2003 Bergman and Stockman introduced the spaser, a quantum amplifier of surface plasmons by stimulated emission of radiation. They argued that, by exploiting a metal/dielectric composite medium, it should be possible to construct a nano-device, where a strong coherent field is built up in a spatial region much smaller than the wavelength. It was suggested that V-shaped metallic inclusions, combined with a collection of semiconductor quantum dots could lead to a realization of the spaser. Here we introduce a further development of the spaser concept. We show that by combining the metamaterial and spaser ideas one can create a planar narrow-diversion coherent source of electromagnetic radiation that is fuelled by plasmonic oscillations. We argue that two-dimensional arrays of a certain class of plasmonic resonators supporting high-Q current excitations belong to a new category of coherent metamaterials that provide an intriguing opportunity to create a spatially and temporally coherent laser source, the Lasing Spaser.
