Intel provided a peek at the future of processors today by revealing the first instance of a chip using complete photonics to send data.
Four lasers in the prototype convert light into data at about 50Gbps, or "many" times faster than wired connections. The rate, about 6.25GB per second, would be enough to send an entire 720p movie in one second.
