High‐Resolution 3D Imaging with Tunable Point Cloud Projection Based on Meta‐Device
Laser &Photonics Reviews, EarlyView.A meta‐based tunable point cloud projection that enables high‐resolution 3D imaging through a dynamic meta‐device is demonstrated. By adjusting spatial sampling, the system achieves significantly sharper reconstructions while remaining compact. The innovation opens new possibilities for applications such as facial recognition, augmented reality, and ...

Reinforcement Learning Enabled Nanophotonic Devices
Laser &Photonics Reviews, EarlyView.A reinforcement learning algorithm is used to design photonic devices. The method creates metagratings and grating couplers that efficiently control both the direction and polarization of light. Further, a reinforcement learning approach is used to design in‐plane integrated photonic devices. This approach paves the way for advanced photonic components

Laser &Photonics Reviews, EarlyView.Manipulating the ultranarrow linewidth spectral features of quasi bound states in the continuum is challenging. A metasurface supporting linear‐to‐linear cross‐polarization coupling efficiency surpassing 25% is proposed to address the issue. Less than 100 nm linewidth is achieved, enabling the device to be applied to wavelength‐selective polarization ...

Laser &Photonics Reviews, EarlyView.Turbid media containing small‐sized Rayleigh‐regime scatterers present a ‘special case’ in which linearly polarized light is found to be less depolarized than circularly polarized light. The underlying mechanisms that give rise to this phenomenon are not yet understood.

Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials
Laser &Photonics Reviews, EarlyView.This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...
