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

Advanced Photonics Research, EarlyView.
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 ...

Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index

Advanced Photonics Research, EarlyView.
Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.

An Ultra‐Wideband Metasurface Perfect Absorber Based on Hybrid Absorption Modes

Advanced Photonics Research, EarlyView.
A Ge2Sb2Te5 metasurface absorber enables polarization‐independent, ultrabroadband (UV–NIR) light absorption with high angular tolerance. Its performance stems from overlapping electric and magnetic dipole resonances in a symmetric structure, achieving 94% average absorption and maintaining 83% even at 70° incidence, promising for integrated ...
