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.

Enhancement of the Ultraviolet Stability of Perovskite Solar by the Interface Modified with Cesium Chloride

Advanced Photonics Research, EarlyView.
CsCl interface modification promotes perovskite growth and suppresses recombination, boosting n–i–p perovskite solar cells (PSC) efficiency from 21.21% to 23.73% and enhancing UV stability fourfold, offering a simple route to efficient, stable PSCs. Stability is an important factor affecting the application of perovskite solar cells (PSCs).

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 ...

Terahertz Chiral Recognition Based on Metasurfaces

Advanced Photonics Research, EarlyView.
A novel terahertz chiral sensing method based on a multilayer metallic metasurface is proposed. The left‐handed circularly polarized and right‐handed circularly polarized components in the linearly polarized illuminating light into two focal points and convert them back into linear polarization for convenient measurement.
