Loss and gain in a plasmonic nanolaser [PDF]

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

Ten years of spasers and plasmonic nanolasers. [PDF]

Light Sci Appl, 2020
AbstractTen years ago, three teams experimentally demonstrated the first spasers, or plasmonic nanolasers, after the spaser concept was first proposed theoretically in 2003. An overview of the significant progress achieved over the last 10 years is presented here, together with the original context of and motivations for this research.

Ultrasmall InGa(As)P Dielectric and Plasmonic Nanolasers. [PDF]

ACS Nano, 2023
Nanolasers have great potential as both on-chip light sources and optical barcoding particles. We demonstrate ultrasmall InGaP and InGaAsP disk lasers with diameters down to 360 nm (198 nm in height) in the red spectral range. Optically pumped, room-temperature, single-mode lasing was achieved from both disk-on-pillar and isolated particles.

Two-dimensional plasmonic waveguides for nanolasing and four-wave mixing [PDF]

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.

Linewidth enhancement in spasers and plasmonic nanolasers [PDF]

Optics Express, 2013
The concept of spaser as the coherent near-field generator and nanolaser based on nanoscale plasmonic resonators has been successfully demonstrated in number of experiments. Here we have developed the theoretical framework for the basic linewidth description of these active plasmonic structures and, in particular, linewidth enhancement - additional ...

Novel non-plasmonic nanolasers empowered by topology and interference effects [PDF]

Nanophotonics, 2021
Historically, nanophotonics deals with a control of light at the nanoscale being closely connected with the rapid advances in plasmonics – the physics of surface plasmon polaritons supported by metal–dielectric interfaces.

Plasmonic Hinge Modes in Metal-Coated Nanolasers. [PDF]

Nano Lett
Plasmonic lasers have traditionally been built on flat metal substrates. Here, we introduce substrate-free plasmonic lasers created by coating semiconductor particles with an optically thin layer of noble metal. This architecture supports plasmonic "hinge" modes highly localized along the particle's edges and corners, exhibiting Purcell factors ...

Plasmonic Bowtie Nanolaser Arrays [PDF]

Nano Letters, 2012
Plasmonic lasers exploit strong electromagnetic field confinement at dimensions well below the diffraction limit. However, lasing from an electromagnetic hot spot supported by discrete, coupled metal nanoparticles (NPs) has not been explicitly demonstrated to date. We present a new design for a room-temperature nanolaser based on three-dimensional (3D)

Plasmonic-nanowire near-field beam analyzer [PDF]

Nanophotonics
Experimental near-field analysis of the output beams from the end faces of micro/nano-waveguide is very necessary, because important information such as spatial intensity distributions, mode orders, and divergence angles can be obtained, and are very ...

Semiconductor nanowire plasmonic lasers [PDF]

Nanophotonics, 2019
Semiconductor nanowires (NW) hold great promise for micro/nanolasers owing to their naturally formed resonant microcavity, tightly confined electromagnetic field, and outstanding capability of integration with planar waveguide for on-chip optoelectronic ...
