'Twisted Light' Shown off in Fibre

Posted June 28, 2013 9:43 AM

From BBC News - Science & Environment:

A novel way of packing more data in optical communications by using "twisted light" is shown to work in optical fibres - with terabit-per-second rates.

Faraday twisted light a while back; I'd like to know how are they going to make every arm of the spiral of a different wavelenght.

Twisted light is different from Faraday rotation. Faraday rotation is the rotation of the angle of plane polarized light traveling within an optically active medium parallel to a magnetic field. Twisted light rotates one or more times within a wavelength. The electric and magnetic field vectors are not perpendicular to the direction of propagation.
