Metasurfaces and metalenses are advancing high-resolution imaging, providing exceptional light control and improving ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240076 , discusses spin-controlled generation of a complete polarization set with randomly-interleaved plasmonic metasurfaces.

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 ...

Researchers have created a bilayer metasurface made of two stacked layers of titanium dioxide nanostructures, opening new possibilities for structuring light. Almost a decade ago, Harvard engineers ...

Imagine manipulating light with ultra-thin, flat sheets instead of bulky lenses and mirrors. That's the promise of metasurfaces, a nanostructure technology that can twist and bend light in ways never ...

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 ...
