Polariton lasing in Mie-resonant perovskite nanocavity

Opto-Electronic Advances
Deeply subwavelength lasers (or nanolasers) are highly demanded for compact on-chip bioimaging and sensing at the nanoscale. One of the main obstacles for the development of single-particle nanolasers with all three dimensions shorter than the emitting ...

How small can “Nano” be in a “Nanolaser”?

Nanophotonics, 2012
We show that the lasing threshold of the single mode metal-semiconductor nano-laser (spaser) is determined only by the photon absorption rate in the metal and exhibits very weak dependence on the composition, shape, size (as long as it is less than half ...

A thresholdless tunable Raman nanolaser using a ZnO–graphene superlattice

, 2017
A ZnO–graphene superlattice is synthesised via a spatially confined reaction. When illuminated by a pump laser, the Stokes' photons of the superlattice are greatly amplified by the surface plasmon at the interface of the graphene and the ZnO. Benefitting

Design and Analysis of a multiple quantum-well plasmonic Germanium/Silicon-Germanium nanolaser

, 2018
There are many researches reported in using Germanium in Silicon based lasers but acquiring this potential for a nanolaser may also be important for development of a CMOS compatible plasmon source. In this paper, a Ge/SiGe multiple quantum well waveguide
