Optically pumped room-temperature GaAs nanowire lasers
Room-temperature lasing in core–shell–cap GaAs/AlGaAs/GaAs nanowires is demonstrated using optical pumping. It is realized by employing a Fabry–Perot cavity along with material optimization and…

Selective-area epitaxy of pure wurtzite InP nanowires: high quantum efficiency and room-temperature lasing.
We report the growth of stacking-fault-free and taper-free wurtzite InP nanowires with diameters ranging from 80 to 600 nm using selective-area metal-organic vapor-phase epitaxy and experimentally…

A nanophotonic laser on a graph
TLDR
A laser based on a nanophotonic network is demonstrated, instead of random scatterers, which allows tailoring of the optical properties and the lasing output via the network topology, and lasing can be tailored and enhanced by the network shape.

Designing single GaAs nanowire lasers
Design parameters for a single GaAs nanowire laser are determined by calculating the threshold gain for nanowire guided modes as a function of nanowire diameter and length. The material gain as a…

Design and Room-Temperature Operation of GaAs/AlGaAs Multiple Quantum Well Nanowire Lasers.
TLDR
It is shown that there is a limit to the minimum and maximum number of QWs that are required for room-temperature lasing and that the TE01 mode, which has a doughnut-shaped intensity profile, is predicted to lase in these nanowire heterostructures, is chosen for the cavity design.

Doping-enhanced radiative efficiency enables lasing in unpassivated GaAs nanowires
TLDR
This work employs controlled impurity doping to increase the rate of radiative recombination and demonstrates lasing from a nanomaterial that combines high radiative efficiency with a picosecond carrier lifetime ready for high speed applications.

Large-Scale Statistics for Threshold Optimization of Optically Pumped Nanowire Lasers.
TLDR
For single nanowire lasers based on bottom-up III-V materials, it is found that low threshold is closely linked to longer lasing wavelength caused by losses in the core, providing a route to optimized future low-threshold devices.
