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.

Plasmonic Bowtie Nanolaser Arrays

TL;DR: A new design for a room-temperature nanolaser based on three-dimensional (3D) Au bowtie NPs supported by an organic gain material is presented and ultrafast resonant energy transfer between photoexcited dye molecules and gap plasmons is confirmed on the picosecond time scale.

Formation of Bound States in the Continuum in Hybrid Plasmonic-Photonic Systems

TL;DR: The strong coupling of photonic waveguide modes are strongly coupled to the gap plasmons in the grating, leading to an avoided crossing behavior with a high value of Rabi splitting of 150 meV and the strong coupling significantly alters the band diagram of the hybrid system, revealing opportunities for supporting stopped light at an off-Γ wide angular span.

Net optical gain in a plasmonic waveguide embedded in a fluorescent polymer

TL;DR: In this article, a long-range surface plasmon propagation with net positive gain over macroscopic distances is directly observed, provided by an optically pumped layer of fluorescent conjugated polymer that is adjacent to the metal waveguide surface.

ZnO nanowire lasers

TL;DR: The mechanism of lasing in ZnO (nanowires) is the subject of a strong debate that is considered at the end of this review, and the special features resulting from the sub-wavelength dimensions are emphasized by presenting the results on single ZNO nanowires lying on a substrate.

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.
