Inside most photonic chips, light races through tiny optical wires. It carries information far faster than electricity can in many conventional systems.

A tiny optical booster built directly onto a chip is pointing toward a future where light, not just electricity, does the heavy lifting inside our computers. By cranking up light signals roughly 100 ...

A new chip uses light instead of electricity to run AI calculations. It processes data very fast and may reduce the power needed for AI systems.

Engineers are turning what used to be a bulky optics bench into something that fits on the tip of a finger, and the latest photonic chips go a step further by splitting a single laser into a ...
