Integration of Laser‐Patterned Photonic Crystals in Si Solar Cells

Advanced Optical Materials, EarlyView.
Photonic crystal textures are integrated into silicon solar cells using laser‐patterned alumina masks and plasma etching. An isotropic defect‐removal process preserves surface passivation and optical quality, enabling 23.1% efficiency. This scalable process with periodically anchored masks and Bessel‐beam patterning marks an important step toward ...

Time‐Efficient Electron Tomography for a Quantitative Description of Chiral Nanorods

Advanced Optical Materials, EarlyView.
To establish structural‐optical property correlations in chiroptically active nanomaterials, conventional electron tomography, which yields 3D reconstructions with nanometric resolution, is a powerful but slow technique. It is demonstrated that fast acquisition schemes afford accelerated characterization of chiral Au nanorods, without loss of quality ...

Bi–Sb Co‐Alloying Tunes Photoexcited State Dynamics in (4FPEA)4AgBi1−xSbxI8 Layered Double Perovskites through Structural Confinement

Advanced Optical Materials, EarlyView.
Lead‐free double perovskites are emerging alternatives to lead‐halide analogues, leveraging low toxicity and highly tunable chemical compositions. These materials possess unique carrier dynamics, often governed by self‐trapped exciton (STE)‐mediated recombination.

Tailoring Chiral Gold Nanorods via Single‐Step Seed‐to‐Au(III) Ratio and Unlocking their Potential in Refractive Index Sensing

Advanced Optical Materials, EarlyView.
A single‐step tunable chiral growth of Au NRs with controllable circular dichrosim (CD) response is reported, and the application of narrow CD response for biosensing with superior Figures of Merit (FoM = RIS/linewidth) over conventional extinction‐based approach in sensitivity is demonstrated.

Phase Smoothing for Mutual Coupling Mitigation in Multifunctional Metasurfaces Designed with Diffractive Neural Networks

Advanced Optical Materials, EarlyView.
A diffractive neural networkdesigned metasurface operating at 86 GHz generates multiple holographic patterns by controlling the phase of subwavelength unit cells. A phase‐smoothing regularization mitigates mutual coupling, enabling accurate multifunctional wavefront shaping.

Photoluminescence Properties of Type‐II GaSb/GaAs Quantum Rings

Advanced Photonics Research, EarlyView.
This study examines the magneto‐optical properties of GaSb/GaAs quantum rings (QRs) using photoluminescence spectroscopy. Recombination dynamics in single‐ and ten‐layer structures are analyzed through activation energy extraction, optical absorption profiling, and observation of a strong excitation‐induced blue shift. Carrier lifetime is also increase
