Scientists in Germany have discovered a technique to produce a pulse of light so short that it contains just a single oscillation of a light wave. Using optical-fibre-optic cables, Alfred Leitenstorfer's group at the University of Konstanz in Germany has found a way to boost data transmission significantly. By reducing the amount of light needed to represent a 1 or 0, binary transmissions can be sent with higher efficiency. This is a fascinating article that discusses a milestone in optical technology that will help in applications like advanced imaging, sensing and signal processing.
