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.

Dipole nanolaser

Physical Review A, 2005
A "dipole" laser is proposed consisting of a nanoparticle and a two-level system with population inversion. If the threshold conditions are fulfilled, the dipole interaction between the two-level system and the nanoparticle leads to coherent oscillations in the polarization of the particles, even in the absence of an external electromagnetic field.

Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

Advanced Photonics Research, Volume 7, Issue 2, February 2026.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

Emission dynamics and spectrum of a nanoshell-based plasmonic nanolaser spaser

Nanophotonics
We study theoretically the emission and lasing properties of a single nanoshell spaser nanoparticle with an active core and a plasmonic metal shell. Using time-dependent equations for the gain medium and metal, we calculate the lasing threshold through ...

Plasmon Enhancement Reveals Origin of the Dark States of Photoluminescence Intermittency in Quantum Dots

Nanophotonics, Volume 15, Issue 2, 27 January 2026.
ABSTRACT Dark states of photoluminescence (PL) intermittency in colloidal quantum dots (QDs) interrupt PL emission and significantly reduce emission intensity, severely hindering QD applications. However, the origin of dark states remains ambiguous due to their extremely low intensity, which impedes the development of effective suppression strategies ...

Self‐Catalyzed AlGaAs Nanowires and AlGaAs/GaAs Axial Heterostructures Grown by Molecular Beam Epitaxy

Advanced Materials Interfaces, Volume 13, Issue 1, 7 January 2026.
Following the parameter modulation described in the manuscript, a high yield of branch‐free self‐catalyzed AlGaAs nanowires at various nominal Al contents with high material quality has been acquired. These branchless structures are ideal hosts for narrower bandgap GaAs quantum dots, promising for non‐classical light‐emitting applications.
