Researchers have clocked light beams made of twisted
waves carrying 2.5 terabits of data — the capacity of more than 66 DVDs — per second.
The technique relies on manipulating what is known as the orbital angular momentum of the waves.
Recent work suggests that the trick could vastly boost the data-carrying capacity in wi-fi and optical fibres.
The striking demonstration of the approach, reported in Nature Photonics, is likely to lead to even higher rates — via redwolf.newsvine.com
