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.

Efficient and Tunable Narrowband Second‐Harmonic Generation by a Large‐Area Etchless Lithium Niobate Metasurface

Laser &Photonics Reviews, EarlyView.
An etchless lithium niobate (LN) metasurface with a slanted periodic TiO2 grating enables efficient and narrowband second‐harmonic generation (SHG) thanks to the light confinement in the LN film granted by quasi‐bound‐state‐in‐the‐continuum (q‐BIC) modes.

Parallel Multi‐Target Detection for Quantum LiDAR

Laser &Photonics Reviews, EarlyView.
Parallel multi‐target detection is achieved in quantum LiDAR with a single‐pixel quantum readout. Direction and distance information are extracted together, allowing multiple objects to be distinguished under noisy low‐light conditions and pointing to a new strategy for scan‐free quantum remote sensing.

High‐Speed Integrated Graphene‐Silicon Slot‐Waveguide Electro‐Absorption Modulator at 2 and 1.5 µm Wavebands

Laser &Photonics Reviews, EarlyView.
A high‐speed, efficient, robust, and compact 2‐μm$\mathrm{\mu}\mathrm{m}$ waveband E/O absorption modulator based on a graphene‐silicon slot waveguide is demonstrated. This work represents a significant advancement towards the realization of high‐speed integrated E/O modulators for optical communication systems operating at the 2‐μm$\mathrm{\mu}\mathrm{
