Achromatic Petal‐Shaped Beam Generation and Information Encoding Based on Perfect Vortex Beam
Nanophotonics, Volume 15, Issue 10, 27 May 2026.Based on petal‐shaped beams with controllable topological charge, size, and rotation angle, this work employs a spatially multiplexed all‐dielectric TiO2 transmissive array to numerically achieve achromatic petal‐shaped beams at three wavelengths: 480 nm, 530 nm, and 630 nm. Leveraging their unique intensity distribution and rotational characteristics,

Terahertz Metasurface for Spatial Detection of Full Stokes Parameters and Polarization Imaging
Nanophotonics, Volume 15, Issue 9, 13 May 2026.This work presents a THz polarization analyzer with significantly improved robustness against nonuniformity. By integrating four polarization‐sensitive meta‐atoms into a meta‐cell, the metalens splits incident light into six polarization components and generates off‐axis focal spots.

Terahertz Encryption With a Polarization‐Sensitive Metasurface
Nanophotonics, Volume 15, Issue 9, 13 May 2026.We propose a dual‐functional terahertz encryption metasurface that enables independent information retrieval in both the near field and the far field within a single device. In the near field, polarization‐selective amplitude modulation reveals textual patterns, whereas in the far field, phase engineering encodes multiple digital data in focal‐spot ...
