PatentDOI
Plasmon lasers at deep subwavelength scale
TL;DR: 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.
Journal ArticleDOI
A hybrid plasmonic waveguide for subwavelength confinement and long-range propagation
TL;DR: In this article, a hybrid optical waveguide is proposed to confine surface plasmon polaritons over large distances using a dielectric nanowire separated from a metal surface by a nanoscale gap.
Journal ArticleDOI
Room-temperature sub-diffraction-limited plasmon laser by total internal reflection
TL;DR: In this paper, a sub-diffraction-limited plasmon laser with low losses is demonstrated, which enables its room-temperature operation, taking a significant step towards realizing the potential of these lasers.
Journal Article
Room temperature sub-diffraction-limited plasmon laser by total internal reflection
TL;DR: A room-temperature semiconductor sub-diffraction-limited laser is presented by adopting total internal reflection of surface plasmons to mitigate the radiation loss, while using hybrid semiconductor-insulator-metal nanosquares for strong confinement with low metal loss.

TL;DR: A high-Q SPP whispering-gallery microcavity that is made by coating the surface of a high- Q silica microresonator with a thin layer of a noble metal is demonstrated and Q factors of 1,376 ± 65 can be achieved in the near infrared for surface-plasmonic whispering- gallery modes at room temperature.
