Researchers at Berkeley’s NSF Nanoscale Science and Engineering Center have successfully used plasmons, a subatomic particle, to create a digital switch. “I’m personally optimistic we’ll see chips like this in ten to twenty years,” says Dr. Thomas Zentgraf, who also notes that light photons don’t collide with each other and “they don’t react with other materials” — so they’ll dissipate less heat and allow much smaller chips and devices. “You can’t move electrons any faster, but photons are constantly going at the speed of light,” says the researcher.
As this article suggests Moore’s law now “starts to look more like a temporary statute,” and light “also has the advantage of being the fastest thing in the universe.”
