Active Switching of Orbital Angular Momentum of Light Using Metasurfaces Incorporating Vanadium Dioxide

Nanophotonics, Volume 15, Issue 5, 16 March 2026.
This work presents a novel design strategy for active metasurfaces that actively switches OAM modes. The metasurface integrates VO2 within MIM meta‐atoms. Operating at 1500 nm, the designed platform enables large leaps in topological charge. For instance, the reflected beam can be switched from a topological charge of −1 in the insulating (M1) phase to

Electrically Tunable On‐Chip Topological Photonics with Integrated Carbon Nanotubes

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
This work demonstrates electrically tunable on‐chip topological THz devices by integrating 2D carbon nanotube (CNT) sheets with valley‐Hall photonic crystals, enabling broadband transmission modulation (71% modulation depth) and tunable narrowband filtering (0.54 GHz shift) through electrically induced thermal tuning. This advancement paves the way for
