TL;DR: In this paper, surface plasmons (SPs) propagating along optically pumped single-graphene layer (SGL) and MGL structures were analyzed and it was shown that at sufficiently strong optical pumping when the real part of the dynamic conductivity of SGL and Mgl structures becomes negative in the terahertz (THz) range of frequencies due to the interband population inversion, the damping of the THz SPs can give way to their amplification.

TL;DR: It is shown that at sufficiently strong optical pumping when the real part of the dynamic conductivity of SGL and MGL structures becomes negative in the terahertz range of frequencies due to the interband population inversion, the damping of the THz SPs can give way to their amplification.

TL;DR: In this article, the spatial distribution of the THz probe pulse intensities under linear polarization of optical pump and probe pulses was observed and the observed gain factor was in fair agreement with the theoretical calculations.

TL;DR: In this article, the authors proposed a terahertz (THz) laser based on the optically pumped graphene layers and the resonant cavity of the Fabri-Perot type.

TL;DR: In this article, a distributed feedback dual-gate graphene-channel field effect transistor (DFB-DG-GFET) was fabricated as a current-injection terahertz (THz) light-emitting laser transistor.
