Silicon Nanophotonics Make Your Gadgets Run Faster, Consume Less

IBM is replacing copper wiring with an avalanche of photons and electrons. They are now transmitting data streams between circuits at the nanophotonic level. Speed: 40Gbps. Power supply: Just 1.5 volts. This video explain how it works.

The system is so fast and consumes so little because of electron avalanches: The receptor - called nanophotonic avalanche photodetector - catches the photon, which starts an electron chain reaction thanks to the properties of Germanium. What does this mean: Faster, smaller and more power efficient devices. And the possibility of saying "nanophotonics" any time we want.
