Photonic AI chip targets faster convolutions with far less energy

Engineers at the University of Florida have built a photonic chip that performs convolutions, the most compute-heavy operation in modern AI, using light instead of electricity and delivering roughly ...

Scientists have finally packed a laboratory-class ultrafast laser onto a tiny photonic chip.

“For more than twenty years, a high-pulse-energy femtosecond laser on chip was widely regarded as a holy grail of integrated photonics,” says Kippenberg. “Our result shows that it is not only possible ...

GF has the photonic chip. Now it has a light source

GF has the photonic IC platform and the packaging but it doesn’t make the lasers. Silicon cannot generate light on its own and still needs semiconductor laser sources.
