(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 ...

Structured light can significantly enhance information capacity, due to its coupling of spatial dimensions and multiple degrees of freedom. In recent years, the combination of structured light ...

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 ...
