Photonics is quietly transforming the future of technology—from AI and high-speed internet to healthcare and energy. Here’s ...

Photonic chips use light to process data instead of electricity, enabling faster communication speeds and greater bandwidth. Most of that light typically stays on the chip, trapped in optical wires, ...

Light has always carried more than brightness. In this case, it also carries direction and twist. That mix may open a new ...

Over the past several decades, researchers have been making rapid progress in harnessing light to enable all sorts of scientific and industrial applications. From creating stupendously accurate clocks ...

In brief: A group of researchers has demonstrated a compact optical device that switches between two distinct topological states of light, marking a key step toward terahertz communication systems ...
