Uncovering Hidden Resonances in Non‐Hermitian Systems with Scattering Thresholds
The points where diffraction orders emerge or vanish in the propagating spectrum of periodic non‐Hermitian systems are referred to as scattering thresholds. Close to these branch points, resonances from different Riemann sheets can tremendously impact the optical response.

Multichannel Detection of Hybrid Spin‐Orbital Mode Pairs
A multi‐foci metalens is developed to detect hybrid spin‐orbital mode pairs (HSOMPs) in multiple channels. Each light spot can detect a predesigned HSOMP, while the spin states of its components are determined by the arc intensity patterns in the neighboring light spots.

Integrated Flat‐Top Beam Shaper Using Subwavelength Engineered Critical Guiding
An integrated flat‐top beam shaper is demonstrated. Subwavelength gratings are utilized to realize the critical guiding of light. The monolithic integrated design provides a scalable solution for high uniformity on‐chip flat‐top beam generation, potential for high‐performance imaging and metrology photonic system.

Decoupling Optical and Thermal Dynamics in Dielectric Metasurfaces for Self‐Encoded Photonic Control
Schematic representation of transmission modulation via photo‐thermo‐optical non‐linearities in a dielectric metasurface. Abstract Thermo‐optical nonlinearities (TONL) in metasurfaces enable dynamic control of optical properties—such as transmitted power, phase, and polarization—through external stimuli like laser irradiation or temperature. Due to the
