Fiber optic lines, the fastest communication media, but still crippled by a key limitation, i.e. data need to be transferred over wires only and this restricts the communication according to the location and fastest connections affordability. Now, scientists have discovered a new way to eliminate those wires, offering even more rapid data-transfer than earlier.
A team of scientists, which includes physicists belonged to the United Kingdom, New Zealand, Canada and Germany, exposed their research on Science Advances. It describes how the team twisted each particle of photons or lights and beamed data into open air that refers to the Optical Angular Momentum (OAM). This may allow transferring data faster than existing fiber optic cables.
The team twisted photons in such a way that not just fills large data into each of the transmission, but also survives disruptions by turbulent air. If light passes via a special hologram, then an optical angular momentum can be given to Photons, which lets them carry more data than only 1s and 0s and so on as intensity and phase of light are right. This data can be beamed reliably over a long distances.
the structured photonics research group head and a leading author of the theory, Dr. Martin Lavery from the at University of Glasgow stated that, “A complete, working optical angular momentum communications system capable of transmitting data wirelessly across free space has the potential to transform online access for developing countries, defense systems and cities around the world.”
