Light normally spreads out rapidly in all directions; a laser coheres the light in a narrow beam. The key to producing this ...

In 1845, Michael Faraday discovered what’s known today as the Faraday Effect—which describes how light and electromagnetism are related. A new study revealed that the magnetic component of light ...

Researchers in China published a paper describing a theoretical model for photonic computing that used light particles instead of electrons for faster processing. The team developed “parallel optical ...

Researchers in Germany have unveiled the Metafiber, a breakthrough device that allows ultra-precise, rapid, and compact control of light focus directly within an optical fiber. Unlike traditional ...

A research team in Bochum, Germany has unexpectedly found that light can slow down movements in the nanoworld. This is due to ...

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 ...
