(Nanowerk Spotlight) Quantum light sources are a fundamental building block for many quantum technologies, enabling secure communication, powerful computing, and precise sensing and imaging.

The study has been published in the journal Nature Communications. To control light, curved lenses are used today, which are often made of glass that is either concave or convex, which refracts the ...

A research team has developed a novel multidimensional sampling theory to overcome the limitations of flat optics. The study not only identifies the constraints of conventional sampling theories in ...

To control light, curved lenses are used today, that are often made of glass that is either concave or convex, which refracts the light in different ways. These types of lenses can be found in ...

Researchers found silica can outperform high-index materials for optical metasurfaces. Its chip-making compatibility enables scalable, robust flat optical devices. (Nanowerk News) An unexpected ...

As anyone who has recently tried out an augmented reality headset knows, the technology is not yet ready to be part of our everyday lives. Researchers have been working to perfect high-performing ...

An unexpected discovery in a Harvard lab has led to a breakthrough insight into choosing an unconventional material, silica, to make optical metasurfaces – ultra-thin, flat structures that control ...

The ability to make both transparent and mirrored surfaces switch between their natural optical behavior and the display of some other form of image has been a fixture in fiction and a challenge in ...

Scanning electron microscopy image of a silica metasurface fabricated at University of Lisbon, with no visible imperfections and tall, cylindrical nanopillars. Harvard SEAS researchers have found that ...
