Two-dimensional plasmonic waveguides for nanolasing and four-wave mixing

New Journal of Physics, 2019
Plasmonic waveguides are an essential element of nanoscale coherent sources, including nanolasers and four-wave mixing (FWM) devices. Here we report how the design of the plasmonic waveguide needs to be guided by the ultimate application.

Loss and gain in a plasmonic nanolaser

Nanophotonics, 2020
Plasmonic nanolasers are a new class of laser devices which amplify surface plasmons instead of photons by stimulated emission. A plasmonic nanolaser cavity can lower the total cavity loss by suppressing radiation loss via the plasmonic field confinement

Plasmon Enhancement Reveals Origin of the Dark States of Photoluminescence Intermittency in Quantum Dots. [PDF]

Nanophotonics
ABSTRACT Dark states of photoluminescence (PL) intermittency in colloidal quantum dots (QDs) interrupt PL emission and significantly reduce emission intensity, severely hindering QD applications. However, the origin of dark states remains ambiguous due to their extremely low intensity, which impedes the development of effective suppression strategies ...

Plasmonic surface lattice resonance and optomechanics for self-assembled nanolasers / [PDF]

, 2022
Plasmonic surface lattice resonance-based (SLR) nanolasers are attractive because of small mode volumes, ultrafast dynamics and good beam directionality. Underlying plasmonic nanocavities are usually produced by standard lithography processes.
