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 ...

A room temperature continuous-wave nanolaser using colloidal quantum wells
Nature Communications, 2017 Colloidal nanocrystals are a promising material for easy-to-fabricate nanolasers, but suffer from high threshold powers. Here, the authors combine colloidal quantum wells with a photonic-crystal cavity into a stable, continuous-wave room-temperature ...

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.

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 ...

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
