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

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

Harvard researchers have found that silica, long thought to lack the right properties for optical metasurfaces, can sometimes ...

Capasso himelf called the discovery “a counterintuitive breakthrough in nanotechnology.” He added, “We have demonstrated in ...

Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to ...

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 ...

Researchers use large language models to streamline nanoscopic material design for advanced optical systems like camera ...

Historically, metasurface research has concentrated on the full manipulation of light's characteristics, resulting in a diverse array of optical devices such as metalenses, metaholograms, and beam ...

A research team has developed a small optical lens, only a few millimeters in size, whose refractive behavior changes in the presence of gas. This 'intelligent' behavior of the micro-lens is enabled ...

Not an aberration: schematic drawing of the metalens (left), which is made of tiny titanium waveguides. The drawing on the right is of a single waveguide. (Courtesy Boubacar Kanté) A new type of ...
