Plasmon lasers are a new class of coherent optical amplifiers that generate and sustain light well below its diffraction limit. Their intense, coherent and confined optical fields can enhance significantly light-matter interactions and bring fundamentally new capabilities to bio-sensing, data storage, photolithography and optical communications. However, metallic plasmon laser cavities generally exhibit both high metal and radiation losses, limiting the operation of plasmon lasers to cryogenic… Expand

The fast-increasing gain at low pump intensity in hybrid plasmonic waveguides is attributed to the transfer across the metal-oxide-semiconductor interface of ‘hot' electrons photogenerated by the pump light. Expand
Cavity-free plasmonic nanolasing enabled by dispersionless stopped light
TLDR
It is revealed that in the absence of cavity-induced feedback, the subwavelength lasing mode forms dynamically as a phase-locked superposition of quasi dispersion-free waveguide modes and offers a new route towards nanolasing, the experimental realization of ultra-thin surface emitting lasers, and cavity-free active quantum plasmonics.
