Uncovering Hidden Resonances in Non‐Hermitian Systems with Scattering Thresholds
Laser &Photonics Reviews, EarlyView.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
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.

Enhancing Realism in Holographic Augmented Reality Displays Through Occlusion Handling
Laser &Photonics Reviews, EarlyView.The proposed optical‐see‐through holographic AR display with occlusion support presents highly realistic 3D AR scenes by projecting speckle‐suppressed, high‐contrast 3D holographic virtual images onto the corresponding real‐scene masks. By leveraging the occlusion capability, virtual shadows based on a Poisson distribution can also be rendered for the ...
