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

In a new leap for neurobiology and bioelectronics, Northwestern University scientists have developed a wireless device that uses light to send information directly to the brain—bypassing the body's ...

Scientists have generated ultra-stable, donut-shaped light structures called skyrmions. These innovative beams can carry data ...

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

“Visible light is much gentler and can penetrate deeper, making it more suitable for real-world applications,” says Huaping Xu, a professor at Tsinghua University and one of the study’s corresponding ...
