Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new way to structure light in custom, repeatable, three-dimensional patterns, ...

A new way to control light using liquid crystals has been developed by researchers in Japan, who believe that their method offers many of the advantages of an artificial “metasurface” while being much ...

(Nanowerk Spotlight) Conventional lenses made of glass can only focus light in a limited way, restricting many potential applications in optics and photonics. Now researchers have developed a new type ...

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light. Lenses are the most widely used ...

A proposed space telescope would focus light primarily with a patterned sheet of metal rather than a large mirror or lens. The telescope would have amazingly sharp vision and could spot Earth-size ...
