Plasmon lasers at deep subwavelength scale
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.read more

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.
