Holography—the science of recording and reconstructing light fields—has long been central to imaging, data storage, and encryption. Traditional holographic systems, however, rely on bulky optical ...

The terahertz (THz) band of the electromagnetic spectrum holds immense promise for next-generation technologies, including high-speed wireless communication, advanced encryption, and medical imaging.

Over the past few decades, engineers have developed various devices that can create holograms, three-dimensional (3D) or ...

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

Metasurface holography harnesses arrays of subwavelength scatterers to impart precise phase, amplitude and polarization control to incident light, enabling ultra-thin holographic elements with ...

Researchers have developed a compact quantum detector that makes terahertz radiation much easier to detect. A specially designed metasurface funnels incoming energy into tiny active regions, greatly ...

A chip smaller than one square millimeter stores 160 holographic images at arbitrary 3D coordinates, with each spatial location functioning as an encryption key. (Nanowerk Spotlight) Most storage ...

(Nanowerk News) Metasurface technology is an advanced optical technology that is thinner, lighter, and capable of precisely controlling light through nanometer-sized artificial structures compared to ...
