Cavity-Volume Scaling Law of Quantum-Dot Metal-Cavity Surface-Emitting Microlasers
IEEE Photonics Journal, 2012 Quantum-dot (QD) metal-cavity surface-emitting microlasers are designed, fabricated, and characterized for various sizes of cavity volume for both lateral and vertical confinements.

Plasmonic Bowtie Nanolaser Arrays [PDF]
Nano Letters, 2012 Plasmonic lasers exploit strong electromagnetic field confinement at dimensions well below the diffraction limit. However, lasing from an electromagnetic hot spot supported by discrete, coupled metal nanoparticles (NPs) has not been explicitly demonstrated to date. We present a new design for a room-temperature nanolaser based on three-dimensional (3D)

Full-Spectrum Analysis of Perovskite-Based Surface Plasmon Nanolasers
Nanoscale Research Letters, 2020 We systematically studied the characteristics of hybrid perovskite-based surface plasmon nanolasers. If one changes the anion composition of perovskites, the emission wavelength can be easily tuned.

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 ...

Novel non-plasmonic nanolasers empowered by topology and interference effects
Nanophotonics, 2021 Historically, nanophotonics deals with a control of light at the nanoscale being closely connected with the rapid advances in plasmonics – the physics of surface plasmon polaritons supported by metal–dielectric interfaces.
