Optical drives let your computer read and interact with discs like CDs, DVDs, and Blu-rays. While nearly every computer had them a few years ago, they're rare to see on new computers now. If you need ...

The constant scaling of AI applications and other digital technologies across industries is beginning to tax the energy grid due to its intensive energy consumption. Digital computing's energy and ...

Although computers are overwhelmingly digital today, there’s a good point to be made that analog computers are the more efficient approach for specific applications. The authors behind a recent paper ...

Microsoft has built a prototype computer that uses light and analog signals instead of traditional binary computing. The system, developed in Cambridge, U.K., is designed to handle optimization tasks ...

“Energy efficiency of electronic digital processors is primarily limited by the energy consumption of electronic communication and interconnects. The industry is almost unanimously pushing towards ...

This new type of optical memory unit,called a programmable photonic latch, is fast and scalable. It could offer a high-speed silicon photonics solution for volatile memory. WASHINGTON — Researchers ...

(Nanowerk News) Conventional computer processors have pretty much maxed out their “clock speeds” — a measurement of how fast they can toggle on and off — due to limitations of electronic switching.

Designing materials that steer light is a slow kind of trial and error. Each candidate structure must be tested in computer ...
