Free-electron nanolaser based on graphene plasmons [PDF]

open access: yesLaser Physics, 2021
Abstract In this paper, a possible way to achieve lasing from the THz to the extreme UV domain due to stimulated scattering of graphene plasmons (GPs) on free electrons is considered. The analytical-quantitative description of the proposed free electron laser scheme is based on a self-consistent set of Maxwell–Vlasov equations.

Multiple Sharp Fano Resonances in a Deep-Subwavelength Spherical Hyperbolic Metamaterial Cavity

open access: yesNanomaterials, 2021
We theoretically study the multiple sharp Fano resonances produced by the near-field coupling between the multipolar narrow plasmonic whispering-gallery modes (WGMs) and the broad-sphere plasmon modes supported by a deep-subwavelength spherical ...

Theory for bowtie plasmonic nanolasers

open access: yesOptics Express, 2008
We develop a fundamental formulation for electrically-pumped plasmonic semiconductor nanolasers based on a metallic bowtie structure. Because of the negative dielectric constant of the metal at optical frequencies, the effective modal volume of the plasmonic mode can be compressed to the nanometer scale.

Plasmonic-photonic crystal coupled nanolaser [PDF]

open access: yesNanotechnology, 2014
We propose and demonstrate a hybrid photonic-plasmonic nanolaser that combines the light harvesting features of a dielectric photonic crystal cavity with the extraordinary confining properties of an optical nano-antenna. In that purpose, we developed a novel fabrication method based on multi-step electron-beam lithography.

Unveiling radial breathing mode in a particle-on-mirror plasmonic nanocavity

open access: yesNanophotonics, 2022
Plasmonic radial breathing mode (RBM), featured with radially oscillating charge density, arises from the surface plasmon waves confined in the flat nanoparticles. The zero net dipole moment endows the RBM with an extremely low radiation yet a remarkable

Plasmonic crystal defect nanolaser

open access: yesOptics Express, 2011
Surface plasmons are widely interesting due to their ability to probe nanoscale dimensions. To create coherent plasmons, we demonstrate a nanolaser based on a plasmonic bandgap defect state inside a surface plasmonic crystal. A one-dimensional semiconductor-based plasmonic crystal is engineered to have stopbands in which surface plasmons are prohibited

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

open access: yes, 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.
