Multichannel Detection of Hybrid Spin‐Orbital Mode Pairs

open access: yesLaser &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.

Compact Spectral Imaging: A Review of Miniaturized and Integrated Systems

open access: yesLaser &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 ...

Enhancing Realism in Holographic Augmented Reality Displays Through Occlusion Handling

open access: yesLaser &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 ...

Customizing 3D Polarization Structures at Second Harmonic Frequency

open access: yesLaser &Photonics Reviews, EarlyView.
The nonlinear optical metasurfaces that can generate second harmonic waves (SHWs) and manipulate 3D polarization structures are designed and fabricated. Based on the concept of nonlinear geometric phase, the desired phase distributions of the SHWs are encoded onto the metasurfaces by using gold C3 meta‐atoms.
