Modern high-performance chips are marvels of engineering, containing tens of billions of transistors. The problem is, you can’t use them all at once. If you did, you would create hot spots—high ...

Microsoft engineers have devised a new way to keep data centers cool — and it might help prevent the next generation of artificial intelligence (AI) hardware from cooking itself to death. The ...

Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical fiber at visible wavelengths. This accomplishment paves the way for a new ...

As artificial intelligence grows more powerful, so does its appetite for speed and energy. The quest for faster, smarter systems has driven researchers to an unlikely ally—light itself. A new study by ...
