Solid‐State Vortex Laser at Eye‐Safe Band: A Perspective

open access: yesNanophotonics, Volume 15, Issue 2, 27 January 2026.
As one of the ideal vortex sources, solid‐state vortex laser at eye‐safe band has attracted considerable attention because of its potentials in multifunctional lidar. In this perspective, we summarize the schemes of eye‐safe vortex laser and discuss prospects for future development.

Phase Modulation for Quadruplex Channels of Arbitrary Orthogonal Polarization States via Bilayer Metasurfaces

open access: yesNanophotonics, Volume 15, Issue 2, 27 January 2026.
This work demonstrates a strategy for four‐channel phase modulation and flexible energy distribution of arbitrary orthogonal states of polarization under incomplete polarization conversion conditions. Such a strategy can be implemented through an all‐dielectric free‐standing bilayer metasurface configuration and can be used for multichannel optical ...

Ambient‐Noise Multicomponent Multimodal Dispersion Characteristics in Thick Sedimentary Basins

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Ambient noise cross‐correlations enable the extraction of multimodal surface waves, yet resolving their complex dispersion characteristics is essential for robust subsurface imaging. Using dense array data from the North China Plain, we resolve multicomponent multimodal Rayleigh and Love wave dispersion with unprecedented detail.
