'Twisted light' carries 2.5 terabits of data per second

From BBC News.
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.
