A completely new structure of light just dropped, called the chiral vortex – and the international team of scientists behind its creation says it could be crucial in developing new drugs and in ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...

As a new degree of freedom, the orbital angular momentum of electromagnetic waves exceeds the traditional frequency, phase, and amplitude, and is expected to promote the infinite expansion of channel ...

A new metasurface lets scientists flip between ultra-stable light vortices, paving the way for tougher, smarter wireless communication.

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 ...

Short pulses from a laser can be twisted into a series of doughnut-like vortices, offering a way to transmit more information using light. We usually encounter vortices in water and air, but similar ...
