While conventional photodetectors can only measure light intensity, the light field contains much richer information. This information includes but is not limited to phase, polarization, and spectrum.

Today, wireless communications play an increasingly important role in our daily lives. For future “freewheeling” sixth generation (6G) wireless communications, the hybrid communication systems that ...

Controlling light is an important technological challenge—not just at the large scale of optics in microscopes and telescopes ...

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

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 ...

Researchers have overcome the limitations of existing metasurface technologies and successfully designed a Janus metasurface capable of perfectly controlling asymmetric light transmission. Metasurface ...

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

Penn State researchers use large language models to streamline metasurface design, significantly reducing the time and ...

Scientists at Sandia National Laboratories and the Max Planck Institute have developed a way to produce a web of quantum entangled photons using a far more simple setup than usual. The key is a ...
