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

Enhanced photon absorption in spiral nanostructured solar cells using layered 2D materials.
TL;DR: This work shows that taking advantage of the mechanical flexibility of 2D materials by rolling a molybdenum disulfide/graphene/hexagonal boron nitride stack to a spiral solar cell allows for optical absorption up to 90%, and expects these results to provide guidance for photonic structures that take advantage of their unique properties in solar energy conversion applications.

Tunable dark plasmons in a metallic nanocube dimer: toward ultimate sensitivity nanoplasmonic sensors
TL;DR: This work theoretically study a silver nanocube dimer and discovers for the first time a dark plasmon with its total loss rate at the lower theoretical limit, which originates from the attractive coupling of the dipolar and quadrupolar mode in the individual nanocubes.

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.
