Quantum plasmonics of metamaterials: loss compensation using spasers

Abstract

The emerging dephasing of harmonics, which form an ideal image, shows up in their destructive interference and breaking of the ideal image. To fulfill the conditions for stimulated emission by an inverted quantum system in the field of the wave previously radiated by this system, the quantum system is placed in a cavity, which localizes the generated model. Due to the high efficiency of this process, an external optical wave which propagates through the metamaterial interacts with entire spasers rather than separately with the amplifying medium and separately with plasmon particles. For the development of metamaterial electrodynamics, however, of interest is the consideration of structures made up of ordered linear or two-dimensional spaser arrays rather than the treatment of a single spaser. Although the presently existing theoretical estimates and experimental realizations in the area of quantum plasmonics rely on quite simple models, they show the promise of using spasers in the development of the elements of optical information facilities and optical computers.
