Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase singularities. While they have been widely studied in recent decades, two ...

Light does not usually surprise people. It travels, it reflects, it bends. In labs, researchers can twist it into more exotic ...

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 ...

An international team of scientists, including researchers from the UAB, has published in Nature Photonics a review on an emerging field that is transforming the way we communicate, measure and ...

Pushing the limits of structured light, applied physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create ...
