Efficient First‐Principles Inverse Design of Nanolasers

Laser &Photonics Reviews, Volume 20, Issue 14, 22 July 2026.
This article introduces a first‐principles inverse‐design framework for nanolasers that directly incorporates nonlinear lasing physics. By unifying steady‐state ab‐initio laser theory (SALT) with topology optimization, it reveals how spatial hole burning, gain saturation, and cavity‐emitter coupling shape laser performance, enabling efficient discovery

Low‐Threshold and Broad‐Wavelength‐Tunable CsPbClxBr3‐x/SiO2/Ag Hybrid Cavity Plasmonic Nanolaser Operated at Room Temperature

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Precise and controllable laser wavelength modulation over a broad spectral range in nanoscale devices is pivotal for advancing next‐generation optoelectronic technologies. Herein, we synthesized high‐quality CsPbBr3 nanowires (NWs) via the anti‐solvent method and constructed a CsPbBr3/SiO2/Ag hybrid structure, demonstrating both photonic and ...

Theory for bowtie plasmonic nanolasers

Optics Express, 2008
We develop a fundamental formulation for electrically-pumped plasmonic semiconductor nanolasers based on a metallic bowtie structure. Because of the negative dielectric constant of the metal at optical frequencies, the effective modal volume of the plasmonic mode can be compressed to the nanometer scale.

Doping-enhanced radiative efficiency enables lasing in unpassivated GaAs nanowires

Nature Communications, 2016
Until now, efforts to enhance the performance of nanolasers have focused on reducing the rate of non-radiative recombination. Here, Burgess et al.employ controlled impurity doping to increase the rate of radiative recombination.

Brillouin Zone Folding‐Driven Topological Band Flips Based on BICs via Twisted Photonic Crystals

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
Brillouin zone folding (BZF)‐driven topological band flips are demonstrated via twisted photonic crystals (PhCs) incorporating bound states in the continuum (BICs). Twist perturbation generates three new bands, each linked to either a BIC or a guided‐mode resonance (GMR).

A quantum optical study of thresholdless lasing features in high-β nitride nanobeam cavities

Nature Communications, 2018
Here the authors present temperature dependent studies of GaN nanobeam lasers grown on a silicon substrate and demonstrate high-βlasing at room temperature. Comprehensive optical and quantum-optical characterization, complemented by microscopic modeling,

Template‐Confined Synthesis of Shape‐Engineered Single‐Crystal Gold Microplates in Lithographically‐Defined Polymeric Patterns

Advanced Functional Materials, Volume 36, Issue 52, 29 June 2026.
Single‐crystal gold microplates are high‐performance nanomaterials with an impressive wafer‐based application space. Progress has, however, been tempered by an inability to exert synthetic control over microplate size, shape, and positioning. In this work, control over these parameters is demonstrated using a seed‐mediated synthesis that both confines ...

Metal-Cavity Nanolasers and NanoLEDs

IEICE Transactions on Electronics, 2012
We present the theory and experiment of metal-cavity nanolasers and nanoLEDs flip-chip bonded to silicon under electrical injection at room temperature. We first review the recent progress on microand nanolasers. We then present the design rule and our theoretical model.
