Lasers make fibre optic tubes out of thin air - tech - 22 July 2014 - New Scientist

Lasers make fibre optic tubes out of thin air - tech - 22 July 2014 - New Scientist: The team shone four lasers in a square arrangement, heating air molecules and creating a low-density ring around a denser core of air. Light bounces around the dense core just like in a fibre.

The air fibre lasts for a few milliseconds – more than enough to send a signal.
