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 ...

(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 ...

Polarization and holographic information become entangled in a quantum hologram. Holographic letters demonstrate entanglement through polarization of paired photons. By selecting different polarizer ...
