Computers that use light instead of circuits to run calculations may sound like a plot point from a Star Trek episode, but researchers have been working on this novel approach to computing for years.

The idea of optical computing—the use of photons instead of electrons to perform computational operations—has been around for decades. However, interest has resurged in recent years; the potential for ...

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...

Modular optical computer chip allows stackable swappable functions By Michael Irving June 20, 2022 MIT engineers have developed a new modular computer chip that uses flashes of light to communicate ...

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 ...

British researchers have created a new material that could allow for the creation of all-optical computers -- computers that are orders of magnitude faster and power efficient than today's hot, sweaty ...

TOKYO--(BUSINESS WIRE)--NTT Corporation (NTT, President & CEO: Jun Sawada, Chiyoda-ku, Tokyo)(TOKYO:9432) in cooperation with the University of Tokyo (President: Teruo Fujii, Bunkyo-ku, Tokyo) and ...

“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 ...

PORTLAND, Ore. — Photonic microchips were enabled Sunday (Feb. 15) by Cornell University's announcement at the American Association for the Advancement of Science (AAAS) in Seattle, of having ...

Fifth-year applied physics Ph.D. candidate Ben Bartlett, postdoctoral scholar Avik Dutt and electrical engineering professor Shanhui Fan proposed a new computer hardware design in November that could, ...
