Ultrahigh Purcell factor in low-threshold nanolaser based on asymmetric hybrid plasmonic cavity [PDF]

, 2016
A low-threshold nanolaser with all three dimensions at the subwavelength scale is proposed and investigated. The nanolaser is constructed based on an asymmetric hybrid plasmonic F-P cavity with Ag-coated end facets.

Tailoring optical fields emitted by nanometric sources [PDF]

, 2014
Here we study a simple way of controlling the emitted fields of sub-wavelength nanometric sources. The system consists of arrays of nanoparticles (NPs) embedded in optical active media. The key concept is the careful tuning of NP's damping factors, which

Design of Surface Plasmon Nanolaser Based on MoS₂

Applied Sciences, 2018
The paper has proposed a new structure based on MoS2. The electric field distribution, the locality and the loss of the mode, and the threshold under different geometric shapes and parameters are investigated using COMSOL Multiphysics software, based on ...

Enhanced Reflection of GaAs Nanowire Laser Using Short-Period, Symmetric Double Metal Grating Reflectors

Nanomaterials, 2022
Owing to the high contrast of the refractive indices at the end facets of a nanowire, lasing emission can be achieved in an individual nanowire without external, reflected feedback.

Zero Crosstalk Regime Direct Modulation of Mutually Coupled Nanolasers

IEEE Photonics Journal, 2017
The modulation properties of dually modulated mutually coupled nanolasers have been analysed using rate equations which include the Purcell cavity-enhanced spontaneous emission factor F and the spontaneous emission coupling factor β.

Structural Engineering in Plasmon Nanolasers [PDF]

Chemical Reviews, 2017
This review focuses on structural engineering of lasers from the macroscale to the nanoscale, with an emphasis on plasmon nanolasers. Conventional lasers based on Fabry-Pérot cavities are limited in device size. In contrast, plasmon nanolasers can overcome the diffraction limit of light and incorporate unique structural designs to engineer cavity ...

Definition of the stimulated emission threshold in high-$\beta$ nanoscale lasers through phase-space reconstruction

, 2011
Nanoscale lasers sustain few optical modes so that the fraction of spontaneous emission $\beta$ funnelled into the useful (lasing) mode is high (of the order of few 10$^{-1}$) and the threshold, which traditionally corresponds to an abrupt kink in the ...
