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 light ...

Researchers at Harvard University, working with collaborators at the University of Lisbon, discovered that low-index silica ...

Researchers have developed a compact, single-shot polarization imaging system that can provide a complete picture of polarization. By using just two thin metasurfaces, the imaging system could unlock ...

Almost a decade ago, Harvard engineers unveiled the world’s first visible-spectrum metasurfaces – ultra-thin, flat devices patterned with nanoscale structures that could precisely control the behavior ...

Think of all the information we get based on how an object interacts with wavelengths of light—aka color. Color can tell us if food is safe to eat or if a piece of metal is hot. Color is an important ...

Researchers created an ultra-thin optical array that controls photons like bulky quantum devices, offering a scalable path to room-temperature quantum photonics. (Nanowerk News) In the race toward ...

New research shows that metasurfaces could be used as strong linear quantum optical networks This approach could eliminate the need for waveguides and other conventional optical components Graph ...
