Light has always carried more than brightness. In this case, it also carries direction and twist. That mix may open a new ...

Manipulation of structured electromagnetic (EM) waves is key to boosting wireless communications capacity. Recently, scientists have invented a space-time-coding metasurface that generates structured ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.230180, discusses orthogonal matrix of polarization combinations: concept and application to multichannel holographic recording.

(Nanowerk Spotlight) Holography, the technique of using light to reconstruct three-dimensional images, has long captured the imagination of scientists and the public alike. By recording and later ...

Copper cabling has been the workhorse for moving data inside of AI and HPC data centers, but fiber is nipping at its heels. Optics brings three possible bandwidth multipliers — wavelength-division ...

A tiny polarization controlled metalens creates a flexible 3D sensor that shifts between precision and long-range modes, offering a new path toward adaptable optical measurement tools. (Nanowerk ...
