Large‐Area Flat Optics Color Routing in Tilted Arrays of 2D Semiconductor Nanostripes

Advanced Optical Materials, EarlyView.
We develop a scalable flat optics platform exploiting self‐organised ion‐beam sputtering and maskless glancing‐angle deposition to fabricate centimetre‐scale arrays of tilted MoS2 nanostripes. The engineered geometry activates Rayleigh anomalies, guided modes, and Mie resonances, enabling highly directional color routing and enhanced light harvesting ...

Robust multiresonant nonlocal metasurfaces by rational design

Nanophotonics
Dielectric metasurfaces supporting optical resonances have become a promising platform for quantum and nonlinear optics. However, resonant metasurfaces remain limited in their capacity to independently control the behavior of many distinct resonances ...

Jones-matrix imaging based on two-photon interference

Nanophotonics, 2022
Two-photon interference is an important effect that is tightly related to the quantum nature of light. Recently, it has been shown that the photon bunching from the Hong–Ou–Mandel (HOM) effect can be used for quantum imaging in which sample properties ...

Electrically Reconfigurable Optical Initialization of Spin Valley Polarization in Monolayer WS2 Enabled by Switchable Dual‐Mode Liquid Crystal Lasers

Advanced Optical Materials, EarlyView.
This work presents an electrically controllable approach to spin–valley polarization in monolayer WS2 by integrating it with a dual‐mode liquid crystal laser. Applying an external field triggers phase transitions that switch the laser emission between helicity‐defined band‐edge lasing and unpolarized random lasing.

Tunable anisotropic van der Waals films of 2M-WS2 for plasmon canalization

Nature Communications
In-plane anisotropic van der Waals materials have emerged as a natural platform for anisotropic polaritons. Extreme anisotropic polaritons with in-situ broadband tunability are of great significance for on-chip photonics, yet their application remains ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
