(Nanowerk News) Researchers have developed a tiny, room-temperature device that creates a special type of structured light called radially polarized photons, which are highly useful for secure ...

An incident plane-wave laser is tuned by a diffractive optical part like grating or prism, and then being transformed into a tilted pulse laser. This tilted pulse is then focused by a sOAP mirror. A ...

Researchers from Wits University and Universitat Autònoma de Barcelona show how controlling the structure of photons in space and time enables tailored quantum states for next-generation communication ...
