Phase-change metasurfaces integrate subwavelength optical architectures with materials whose refractive index and absorption can be dynamically and reversibly altered through an external stimulus, ...

A research team has demonstrated the first nonlinear metasurface with engineered nonlocality, that simultaneously delivers high‑Q resonance enhancement and pixel‑level control of the wavefront of ...

(a) Schematic of non-local mode selection by metasurface-integrated quantum analog operation. F^1, F^2, F^3, and F^4 are the differential operators. The green area has been designed to construct ...
