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.

Mode‐Locked Pulse Generation in Plasmonic Lattices
Laser &Photonics Reviews, Volume 20, Issue 7, 6 April 2026.The plasmonic superlattices overlaid with optically pumped organic molecules produce multimode lasing due to mid‐range radiative coupling (MR‐RC, lambda) and long‐range radiative coupling (LR‐RC, 10 lambda). Right: The mode locking emerges spontaneously due to the shared excited state molecular populations which may emit photons to various different ...

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.

Multiplexing Two Types of High‐Order Topological Corner States in Kagome Lattice Photonic Crystals
Nanophotonics, Volume 15, Issue 8, 24 April 2026.Higher‐order topological corner states in kagome photonic crystals exhibit a direction‐wavelength locking mechanism: two corner states with distinct resonant frequencies couple to different output channels. Harnessing this effect, a 1 × 2 wavelength demultiplexer achieves low‐crosstalk signal separation, demonstrating the potential of topological ...

Carrier Transport in Electrically‐Driven Photonic Crystal Membrane Lasers
Laser &Photonics Reviews, Volume 20, Issue 5, 6 March 2026.A model to study carrier transport in photonic crystal lasers with a buried heterostructure active region and a lateral current injection scheme is presented. The model identifies unconventional leakage paths which explain low injection efficiencies and enhanced recombination at the p‐doping interface observed experimentally.
