Facebook has created a new way of detecting optical communication signals travelling through the air, by using lasers.
The findings, which Facebook say could 'pave the way for the optical wireless networks', are documented in the Optica journal.
HOW DOES IT WORK?
Current methods to connect to wireless networks require optical fibres and cell towers - which can be challenging to deploy in remote areas.
Instead, using lasers to carry information through the atmosphere could offer high bandwidths and data capacity as a cost-effective alternative.
The device uses fluorescent materials instead of traditional optics to collect light and concentrate it on to a small photodetector.
Because the fluorescent materials do not emit the same colour they are absorbing, a brighter light can be turned around in under two nanoseconds.
