3D Meta‐Atoms for High Confinement of Mid‐IR Radiation

Advanced Optical Materials, EarlyView.
Mid‐infrared, three‐dimensional circuit‐like resonators with extreme field confinement are experimentally demonstrated. Combining simulations, measurements, and analytical modelling, a physical interpretation and prediction of the resonant modes supported by the structure, including their resonant frequency and radiative and non‐radiative losses, is ...

Spin‐Valley Polarization Control in WSe2 Monolayers using Photochemical Doping

Advanced Optical Materials, EarlyView.
A photochemical doping method is employed to modulate the spin‐valley polarization in WSe2 monolayers by tuning the carrier density from electron‐rich to hole‐rich regimes. This controlled doping enables a three‐fold variation in exciton polarization, revealing relaxation channels driven by scattering between excitons and charge carriers in two ...

Ellipticity‐Controlled Exceptional Points and Cross‐Polarized Phase Singularities in Multi‐Layer Silicon Guided Mode Resonant Metasurfaces

Advanced Optical Materials, EarlyView.
Omni‐polarizers that pull all input polarization states to an elliptical or linear polarization can be made using highly resonant bi‐layer metasurfaces. The ellipticity of the selected polarization can be controlled by choosing the layer separation.

Liquid Metal‐Exfoliated SnO2‐Based Mixed‐Dimensional Heterostructures for Visible‐to‐Near‐Infrared Photodetection

Advanced Optical Materials, EarlyView.
Two dimensional (2D) atomically thin materials hold significant promise for next‐generation photodetectors but are limited by low light absorption and scalability challenges. This study presents a high‐performance photodetector integrating liquid metal‐derived 2D SnO2 with CdTe, enabling efficient visible to near‐infrared detection and offering a ...

High‐Endurance and Energy‐Efficient All‐Optical Programming of Scalable Silicon Waveguides with Integrated Phase‐Change Material Patches

Advanced Optical Materials, EarlyView.
Phase change materials are integrated into silicon photonic circuits via 200 mm industrial wafer processes. Interferometric optical characterization reveals switching thresholds, transmission modulation, phase shifts, and record endurance (>108 cycles).

Broadband Measurement and Tuning of the Volatile Thermo‐Optic Properties in Chalcogenide Phase Change Materials

Advanced Optical Materials, EarlyView.
Chalcogenide phase change materials (PCMs) demonstrate a significant switchable volatile thermo‐optic response across visible and telecommunication bands. A broadband measurement is presented showing that some alloys exceed traditional reconfigurable materials in photonic integrated circuit (PIC) applications.
