A new study from the University of Dundee could open up a new era of superfast communications technology and lead to breakthroughs in the treatment of medical conditions such as Alzheimer’s.
Particles of light can, in principle, carry and deliver an unlimited amount of information between two remote places. The information can be encoded into the shape of photons, which then travel through a communication channel and are decoded at the end point.
A problem arises, however, when the information encoded to the photon shapes gets scrambled as the fibre is looped or bent or when the fibre suffers by even very tiny imperfections. For a very long time, such fibres were believed to be, in essence, equivalents of permanently changing Enigma machines to which nobody holds the key.
