Multichannel Detection of Hybrid Spin‐Orbital Mode Pairs
Laser &Photonics Reviews, EarlyView.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
Laser &Photonics Reviews, EarlyView.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
Laser &Photonics Reviews, EarlyView.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

Compact Spectral Imaging: A Review of Miniaturized and Integrated Systems
Laser &Photonics Reviews, EarlyView.This review explores the rapid shift toward compact spectral imaging systems by examining four key design paradigms: Do‐It‐Yourself (DIY) platforms, freeform optics, filter‐on‐chip integration, and multifunctional metasurfaces. The discussion highlights critical applications in medicine, agriculture, and environmental monitoring, providing comparative ...
