TLDR
Hybrid plasmonic waveguides as discussed by the authors employ a high-gain semiconductor nanostructure functioning as a gain medium that is separated from a metal substrate surface by a nanoscale thickness thick low-index gap.
Abstract
Hybrid plasmonic waveguides are described that employ a high-gain semiconductor nanostructure functioning as a gain medium that is separated from a metal substrate surface by a nanoscale thickness thick low-index gap. The waveguides are capable of efficient generation of sub-wavelength high intensity light and have the potential for large modulation bandwidth >1 THz.

Anomalous spectral scaling of light emission rates in low-dimensional metallic nanostructures

TL;DR: In this article, it was shown that light-matter interactions in plasmonic systems confined in two dimensions (e.g., near metal nanowires) strengthen with decreasing frequency owing to strong mode confinement away from the surface-plasmon frequency.

Surface plasmon enhanced electrically pumped random lasers

TL;DR: Electrically pumped random lasing has been realized in Au/MgO/ZnO structures by incorporating Ag nanoparticles, whose extinction spectrum overlaps well with the emission spectrum of the structures, and the threshold of therandom lasing can be decreased from 63 mA to 21 mA.

Tunable 3D Dirac-semimetals supported mid-IR hybrid plasmonic waveguides.

TL;DR: In this article, the effects of Fermi levels, structural parameters, and operation frequency on the tunable propagation properties of hybrid waveguides were investigated, and the results showed that if the operation frequency is smaller (larger) than the transition frequency (ℏω≈2|μc|), the proposed hybrid waveguide indicate strong (weak) confinement because the DSM layer manifests a high plasmonic low) loss property.

Single-nanowire electrically driven lasers

TL;DR: In this paper, the authors investigate the feasibility of achieving electrically driven lasing from individual nanowires and show that these structures can function as Fabry-Perot optical cavities with mode spacing inversely related to the nanowire length.
