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 ...

Over the past decade, metasurfaces deploying two-dimensional artificial nanostructures have emerged as a groundbreaking platform to manipulate light across various degrees of freedom. These ...

Tailored profiles: The working principle of the new metalaser. The designed geometric phase profile is introduced to the metasurface by rotating the hole in each silicon nitride nanodisk. Then the ...

Have you ever wished to drive microscopic matter along an arbitrarily tailored trajectory instead of just a circle? That's ...

Layered metasurfaces trained as optical neural networks enable multifunctional holograms and security features, integrating neural computation principles with nanostructured optics to create a ...

Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field rotates. The other comes from the shape of the wavefront itself, which can ...

Changing light's polarization can reverse the structure of a patterned light field, opening a new way to control geometry and information in optics. (Nanowerk Spotlight) Light can be bent, focused, or ...
