‘Twisted light’ carries 2.5 terabits of data per second

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
