Photonic chips process and transmit information using light instead of electricity, guiding photons through microscopic structures on a chip.

A tiny optical booster built directly onto a chip is pointing toward a future where light, not just electricity, does the ...

Quantum communication has long promised unbreakable encryption, but the hardware has struggled to escape the lab. A new generation of laser-written glass chips is changing that equation, carving three ...

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 ...
