Broadband Parametric Amplification in AlGaAs‐on‐Insulator Nanowaveguides

Laser &Photonics Reviews, EarlyView.
Harnessing the exceptional nonlinearity of AlGaAs‐on‐insulator nanowaveguides, four‐wave‐mixing parametric amplification achieves a record net on‐chip gain of 56 dB and a gain bandwidth exceeding 415 nm at telecom wavelengths. These results establish AlGaAsOI as a powerful platform for compact, high‐performance integrated nonlinear optical ...

Reconfigurable Giant Nonreciprocity at Near‐Normal Incidence via Phase‐Change Magneto‐Optical Metagratings

Laser &Photonics Reviews, EarlyView.
A phase‐change magneto‐optical metagrating combines GST switching with InAs guided‐mode resonances to achieve strong nonreciprocal absorption contrast near normal incidence. A static magnetic bias creates direction‐dependent resonant splitting, while GST crystallization quenches and latches the response.

Rapid Discovery of TiO2/ZnFe2O4/Cu Ternary Photocatalysts for Volatile Organic Compounds Degradation via High‐Throughput Screening Photogenerated Carriers Transfer Properties

Materials Genome Engineering Advances, EarlyView.
This study develops a high‐throughput screening method using carrier mobility as a key descriptor. Taking the TiO2/ZnFe2O4/Cu ternary photocatalytic system as an example, we rapidly identify high‐performance components for VOCs degradation, confirm that the performance trends of thin‐film catalysts match those of their powder counterparts with the same

Amorphous Monolayer MoS3 Nanosheets for Rapid and Robust Sodium‐Ion Storage

National Materials, EarlyView.
Amorphous monolayer MoS3 nanosheets synthesized via interface‐confined wet chemistry exhibit high capacity, excellent rate capability, and long cycling stability for sodium‐ion storage. The isotropic monolayer structure enables fast Na+ diffusion and reversible Mo‐S bond reconstruction, providing a strategy for high‐performance amorphous electrode ...
