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 ...

Color-changing mood rings, forehead fever strips and car-shade indicators all change hues as they warm and cool, thanks to a ...

A team of researchers has developed a way to significantly increase the memory of speckle patterns, the very complex patterns that result from shining a laser light onto an opaque sheet, such as paper ...

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 ...

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 ...

Zoe Kleinmann and a student make a pattern of light with translucent cups. Zoe Kleinmann and a student explore patterns. First they create units of two connected plastic cubes to create an AB pattern.

Disco ball light bulb transforms an ordinary room into a vibrant party space with moving light patterns and colorful ...

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 ...

NTT’s research division has developed what it claims to be the world’s first programmable nonlinear photonic waveguide capable of switching between multiple nonlinear-optical functions on a single ...
