New Scientist : : A team of optical engineers has found a way to circumvent attenuation in light signals that travel along optical fibers. David Richardson at the University of Southampton in the UK and his colleaguesâmdash;whose results were published in Nature Photonics âmdash;have found a way to reverse the degradation process and re-create the original signal. In addition, whereas data have conventionally been sent as a series of on–off light pulses, the researchers propose to squeeze more data onto a stream of light by using the amplitude and phase of the optical carrier. The technique portends better web video, among other things.
