Like a whirlpool, a new light-based communication tool carries data in a swift, circular motion. Described in a study published last week by the journal Science, the optics advancement could become a ...

A laser beam converted to an optical vortex can perform laser-induced forward transfer (LIFT) of ferrite nanoparticles resulting in twisted single crystals corresponding to the rotation of the vortex.

In recent years, optical vortices have attracted extensive attention in laser advanced manufacturing because of their annual intensity distribution and orbital angular momentum. Compared with the ...
