BaTiO3/TiO2 Hybrid Metasurface for Free-space Electro‑optic Modulators
We demonstrate a free-space active metasurface based on a BaTiO 3 /TiO 2 heterostructure, enabling CMOS-compatible electro-optic tuning of a high-Q guided mode resonance at 1579.8 nm, achieving a significant tuning rate of ~0.43 nm/(V/μm).
