An unexpected discovery in a Harvard lab has led to a breakthrough insight into choosing an unconventional material, silica, ...

WASHINGTON — For the first time, researchers have created a metasurface lens that uses a piezoelectric thin film to change focal length when a small voltage is applied. Because it is extremely compact ...

Currently, Kyocera's technology enables aerial images whose focal positions vary by color. In the future, increasing the ...

A team of researchers at Penn State have devised a new, streamlined approach to designing metasurfaces, a class of engineered ...

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 ...

Given their tiny size, individual atoms are notoriously tricky to see and manipulate, but finding ways to do so would be extremely useful. The invention of the laser in the 1960s eventually led to the ...

Kyocera has developed a new ultra-thin meta-lens that can shift focal positions depending on the wavelength of light.

Lenses with tunable focusing capabilities are attractive for a range of operations, including several bioimaging operations where speed of image capture is critical. Metasurfaces can offer a route to ...

Micro-sized cameras have great potential to spot problems in the human body and enable sensing for super-small robots, but past approaches captured fuzzy, distorted images with limited fields of view.

(Nanowerk News) For the first time, researchers have created a metasurface lens that uses a piezoelectric thin film to change focal length when a small voltage is applied. Because it is extremely ...
