Today, most information is transmitted by light – for example in optical fibers. Computer chips, however, work electronically. Somewhere between the optical data highway and the electronic chips, photons have to be converted into electrons using light-detectors. Scientists have now managed to combine a graphene photodetector with a standard silicon chip. It can transform light of all important frequencies used in telecommunications into electrical signals.
