In this paper, we propose a structure for graphene spaser and develop an electrostatic model for quantizing plasmonic modes. Using this model, one can analyze any spaser consisting of graphene in the electrostatic regime. The proposed structure is investigated analytically and the spasing condition is derived. We show that spasing can occur in some frequencies where the Quality factor of plasmonic modes is higher than some special minimum value. Finally, an algorithmic design procedure is…

Spaser made of graphene and carbon nanotubes.
TLDR
A carbon-based spaser design in which a graphene nanoflake resonator is coupled to a carbon nanotube (CNT) gain element and it is theoretically demonstrate that the optically excited CNT can nonradiatively transfer its energy to the localized plasmon modes of the GNF because of the near-field interaction between the modes and the CNT excitons.

Electric spaser in the extreme quantum limit.
TLDR
The electrically pumped spaser is promising as an optical source, nanoamplifier, and digital logic device for optoelectronic information processing with a speed of ~100 GHz to ~100 THz.
Energy equipartition and unidirectional emission in a spaser nanolaser
A spaser is a nanoplasmonic counterpart of a laser, with photons replaced by surface plasmon polaritons and a resonant cavity replaced by a metallic nanostructure supporting localized plasmonic
Demonstration of a spaser-based nanolaser
TLDR
It is shown that 44-nm-diameter nanoparticles with a gold core and dye-doped silica shell allow us to completely overcome the loss of localized surface plasmons by gain and realize a spaser, and that outcoupling of surface plasmon oscillations to photonic modes at a wavelength of 531 nm makes this system the smallest nanolaser reported to date—and to the authors' knowledge the first operating at visible wavelengths.
Quantum theory of a spaser-based nanolaser.
TLDR
A quantum theory of a spaser-based nanolaser, under the bad-cavity approximation, is presented, which allows to understand the fundamental principles of operation of nanolasers.

Two-dimensional gas of massless Dirac fermions in graphene
TLDR
This study reports an experimental study of a condensed-matter system (graphene, a single atomic layer of carbon) in which electron transport is essentially governed by Dirac's (relativistic) equation and reveals a variety of unusual phenomena that are characteristic of two-dimensional Dirac fermions.
