Capturing precise 3D details with a single camera has long been a challenge. Traditional methods often require complex ...

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

Metasurfaces are a promising type of new nanophotonic technology. A metasurface was recently used at Harvard to create an ultrathin, flat lens that focuses light without imparting the optical ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only ...

A laser beam hits a meta-grating that directs the light waves even at steep incidence angles, thus enabling new optical ...

(Nanowerk Spotlight) Light carries information in its wavelength, wavevector direction, polarization, and the way it bends through materials. Until now, optical data storage has typically used just ...

Meta-optics is a rapidly emerging field that combines the principles of metamaterials and optical engineering to control and manipulate light in unprecedented ways. It involves the design and ...
