NTT researchers develop breakthrough optical memory device

(PhysOrg.com) -- To improve transmission speeds, the Internet has transitioned over the years from one using copper to fiber optic cabling. Unfortunately, this has caused a bottleneck to occur where the light signals meet with electronic circuitry. Researchers have been working for years on a way to make routers, and most particularly, their memory, all optic, to avoid having to convert the signals at all. Now, it appears one such group, NTT, a Japanese telecommunications company, has figured out a way to do it. They describe their work in a paper published in Nature Photonics.
