How to Avoid Congestion on Information Superhighways
data is transmitted via fiber optic cables and light pulses generated by semiconductor lasers at the cables’ connecting points. Every single light pulse comprises many thousands of photons, each one of which [...] reduce the number of photons contained in each signal pulse. For quite some time now, physicists have been able to build light sources using light pulses comprising low numbers of photons, and in an extreme [...] Manfred Bayer in Dortmund have succeeded in visualizing the individual photons contained in light pulses in a way that resembles flows of traffic. They do this using the special nanolasers built by Professor
