Thresholdless quantum dot nanolaser

open access: yesOptics Express, 2017
Thresholdless lasing is an outstanding challenge in laser science and is achievable only in devices having near unity quantum efficiency even when not lasing. Such lasers are expected to exhibit featureless linear light output curves. However, such thresholdless behavior hinders identification of the laser transition, triggering a long-lasting argument

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

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.

Measuring the frequency response of optically pumped metal-clad nanolasers

open access: yes, 2019
We report on our initial attempt to characterize the intrinsic frequency response of metal-clad nanolasers. The probed nanolaser is optically biased and modulated, allowing the emitted signal to be detected using a high-speed photodiode at each ...

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.

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 ...

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.

Inverse Design of Whispering-Gallery Nanolasers with Tailored Beam Shape and Polarisation

open access: yes, 2022
The aim of this thesis is to design the shape of nanocavities to tailor their radiated beam in terms of intensity and polarisation distribution, and emission direction.
