Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as ...

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

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

A new Israeli study suggests that light can directly influence materials in a magnetic field in ways scientists had long overlooked, a finding that could affect technologies from fiber-optic ...
