Dynamics of Electrically Pumped Semiconductor Nano-Laser Arrays

Photonics, 2023
Semiconductor nano-lasers have been actively investigated both theoretically and experimentally with to the aim of providing a highly compact laser amenable to photonic integration.

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)

Multiple Bound States in the Continuum in Deep‐Subwavelength Nonlocal Polar Dielectric Nanoparticles

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
Spatial dispersion in polar‐dielectric core–shell nanoparticles enable multiple deep‐subwavelength bound states in the continuum through longitudinal‐transverse hybrid modes. By suppressing radiative damping at finite geometrical parameters, these nonlocality‐induced BICs provide a compact platform for high Q light confinement, enhanced light–matter ...

Beyond periodicity: tailoring Tamm resonances in plasmonic nanohole arrays for multimodal lasing

New Journal of Physics
Extraordinary optical transmission (EOT) through metal nanohole arrays (NHAs) and Tamm plasmon (TP) states have been investigated in plasmonic devices since 1998 and 2007, respectively.

Electromagnetic analysis of the lasing thresholds of hybrid plasmon modes of a silver tube nanolaser with active core and active shell

Beilstein Journal of Nanotechnology, 2019
Results from the electromagnetic modeling of the threshold conditions of hybrid plasmon modes of a laser based on a silver nanotube with an active core and covered with an active shell are presented. We study the modes of such a nanolaser that have their

Tunable Unidirectional Guided Resonances via Multi‐Singularity Interactions in Momentum Space

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
C points can intrinsically coexist around symmetry‐protected BICs without symmetry reduction. Symmetry breaking splits SP‐BICs into new C points that interact with intrinsic ones, forming perfect UGRs at distinct k points with tunable topological charges.

Plasmonic crystal defect nanolaser

Optics Express, 2011
Surface plasmons are widely interesting due to their ability to probe nanoscale dimensions. To create coherent plasmons, we demonstrate a nanolaser based on a plasmonic bandgap defect state inside a surface plasmonic crystal. A one-dimensional semiconductor-based plasmonic crystal is engineered to have stopbands in which surface plasmons are prohibited

Stress Accumulation Induced by Ion Exchange for Synchronous Modulation of Mode and Wavelength in Microlasers

Advanced Science, Volume 13, Issue 48, 28 August 2026.
This work demonstrates a paradigm‐shifting strategy to simultaneously achieve broadband wavelength tunability and single‐mode control within a single perovskite microwire structure. Using a facile heating‐assisted solid–solid anion‐exchange strategy, we synthesized phase‐pure CsPbClxBr3‐x microwires that exhibit the widest reported continuous lasing ...

Wavelength and Pulsewidth Tunable Flexible CsPbBr3 Perovskite Microlasers by Mechanical Stress Modulation

Advanced Electronic Materials, Volume 12, Issue 15, 10 August 2026.
Mechanically tunable all‐organic CsPbBr3 perovskite microlasers on a flexible PET substrate is demonstrated, enabling simultaneous wavelength and pulsewidth modulation of laser emission. The strain–photon synergetic coupling mechanism is revealed.

Overcoming Computational Bottlenecks in Quantum Hydrodynamics: A Volume‐Based Integral Formalism for Spherical Nanoparticles

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Numerical modeling of mesoscopic material response models that capture the quantum dynamics of electrons does not have to come with discouraging computational bottlenecks. The main message is that through a shift in perspective in modeling toward integral equation methods and exploiting symmetry‐based arguments, it is possible to capture complicated ...
