Lead‐Free Chiral Hybrid Metal Halides for Circularly Polarized Light‐Emitting Diodes

Advanced Optical Materials, EarlyView.
Lead‐free chiral hybrid metal halides provide a versatile platform for realizing chiroptical responses through chiral modulation of metal–halide frameworks with diverse dimensionalities, induces inversion‐symmetry breaking and enables dissymmetric excited‐state transitions toward efficient circularly polarized luminescence and electroluminescence.

Rotating Fluorescent Nanodiamond Assemblies With Focused Laguerre–Gaussian Beams

Advanced Optical Materials, EarlyView.
Self‐assembled fluorescent nanodiamond clusters are optically trapped and driven into controlled two‐dimensional rotation with Laguerre–Gaussian beams. With localized optical excitation, optically detected magnetic resonance spectra are collected at defined points along the orbit in a uniform external magnetic field.

Deterministic Transferable Planar Dielectric Mirrors for Investigating Strong Light–Matter Coupling

Advanced Optical Materials, EarlyView.
Transferable dielectric distributed Bragg reflectors enable the deterministic assembly of high‐quality planar microcavities while maintaining the intrinsic properties of quantum materials during fabrication. The resulting structures exhibit robust exciton‐photon coupling in monolayer WS2${\rm WS}_{2}$ from cryogenic to room temperature, establishing a ...

From Molecular Design to Optical Anisotropy: Orientation Control in BODIPY Langmuir‐Blodgett Films

Advanced Optical Materials, EarlyView.
The supramolecular organization of amphiphilic boron‐dipyrromethene (BODIPY) dyes in Langmuir–Blodgett monolayers is shown to govern their optical anisotropy. By correlating nanoscale imaging and angle‐resolved spectroscopy, we reveal symmetry‐driven control of transition dipole orientation, enabling either in‐plane or out‐of‐plane optical responses ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
