Learn about the optical rotatum, a newfound structure of light that exhibits a spiral pattern linked with various parts of ...

Beams of light that can be guided into corkscrew-like shapes called optical vortices are used today in a range of ...

Light doesn’t just travel in straight lines—it can also twist. And when it does, it opens new frontiers in science and medicine. A recent breakthrough led by Professor Igor Meglinski at Aston ...

The researchers also introduced a spiral phase plate to the 1553-nm beam before frequency mixing, resulting in the generation of a vortex beam carrying orbital angular momentum. This marks the ...
