1000 times more efficient nano-LED opens door to faster microchips

The electronic data connections within microchips are increasingly becoming a bottleneck in the exponential growth of data traffic. Optical connections are the obvious successors but optical data transmission requires an adequate nanoscale light source, and this has been lacking. Scientists have created a light source that has the right characteristics: a nano-LED that is 1000 times more efficient than its predecessors, and is capable of handling gigabits per second.
