Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics

Laser &Photonics Reviews, Volume 20, Issue 14, 22 July 2026.
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Contact Lens with Moiré Patterns for High‐Precision Eye Tracking

Advanced Functional Materials, Volume 36, Issue 29, 9 April 2026.
This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.

Leveraging Plasmonic Nanocavity Arrays Forming Metasurfaces to Boost Second Harmonic Generation Due to Surface Effects

Advanced Optical Materials, Volume 14, Issue 9, 6 March 2026.
Second harmonic generation (SHG) typically requires non‐centrosymmetric crystals to be realized. Here, we experimentally demonstrate a 105‐fold boost in the SHG response from centrosymmetric materials by realizing gold nanocavity arrays forming plasmonic metasurfaces.

Dislocations in twistronic heterostructures

2D Materials
Abstract Long-period moiré superlattices at the twisted interface of van der Waals heterostructures relax into preferential stacking domains separated by dislocation networks. Here, we develop a mesoscale theory for dislocations in networks formed in twistronic bilayers with parallel (P) and antiparallel (AP) alignment of unit cells ...
