Hybrid gap plasmon GaAs nanolasers [PDF]

open access: yes, 2017
Compact semiconductor lasers with sub-wavelength-scale dimensions rely heavily on materials with low surface recombination due to the large surface area to volume ratios of their nano-cavities.

Ultrastrong Mode Confinement in ZnO Surface Plasmon Nanolasers

open access: yes, 2015
Nanolasers with an ultracompact footprint can provide high-intensity coherent light, which can be potentially applied to high-capacity signal processing, biosensing, and subwavelength imaging.

Ultrafast pulse generation in integrated arrays of anapole nanolasers [PDF]

open access: yes, 2017
One of the main challenges in photonics is the integration of ultrafast coherent sources in silicon compatible platforms at the nanoscale [1]. Generally, the emission of ultra-short pulses is achieved by synchronizing the cavity modes of the system via ...

Electrically Pumped Metallo-dielectric Pedestal Nanolasers With High Thermal-conductivity Shield

open access: yes, 2015
We implement amorphous-Al2O3 as thermally-conductive shield in metallo-dielectric nanolasers, and demonstrate an electrically pumped device. Joint consideration of various design parameters reveals that this design allows the laser to dissipate heat ...

Quantum theory of a spaser-based nanolaser

open access: yesOptics Express, 2014
We present a quantum theory of a spaser-based nanolaser, under the bad-cavity approximation. We find first- and second-order correlation functions $g^{(1)} (τ)$ and $g^{(2)}(τ)$ below and above the generation threshold, and obtain the average number of plasmons in the cavity. The latter is shown to be of the order of unity near the generation threshold,

Stochastically sustained population oscillations in high-β nanolasers

open access: yesNew Journal of Physics, 2013
Nonlinear dynamical systems involving small populations of individuals may sustain oscillations in the population densities arising from discrete changes in population numbers due to random events.

Plasmonic Nanolasers Enhanced by Hybrid Graphene–Insulator–Metal Structures

open access: yes, 2019
Graphene is a two-dimensional (2D) structure that creates a linear relationship between energy and momentum that not only forms massless Dirac fermions with extremely high group velocity but also exhibits a broadband transmission from 300 to 2500 nm that

A nanolaser with extreme dielectric confinement

open access: yesScience Advances
The interaction between light and matter can be enhanced by spatially concentrating the light field and extending photon dwell time. Plasmonic structures can provide strong light confinement but suffer from ohmic losses. Recent advances in dielectric nanostructures enable strong light localization without metallic losses.

Delayed formation of coherence in the emission dynamics of high-Q nanolasers

open access: yes, 2018
In the realization of ultrasmall semiconductor lasers, cavity-QED effects are used to enhance spontaneous emission and enable the lasing threshold to be crossed with gain contributions from only a few solid-state emitters.
