Traditional fiber-optic communication sends data using just one light pattern. That’s fine, but it means the amount of bandwidth that a fiber strand can deliver is limited. If you could add more light ...

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 at the University of the Witwatersrand (Wits) have developed a "light-powered brain" that can recognize hidden information in complex patterns of light, potentially paving the way for ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called skyrmions. These light vortices hold their shape even when disturbed, making them ...

A flexible optical identifier uses polarized emission from self-assembled crystal films to create two stable states that support tri modal authentication and improve reliability in secure device ...

In a recent article published in Nature communications*, researchers described a technique of capturing two-dimensional (2D) light patterns into deoxyribonucleic acid (DNA) and using high-throughput ...

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 ...
