Bandwidth is a measure that is on the back of the minds of everyone that use the internet. Don't you just wish you had a seamless connection with data speeds not varying due to excess traffic? Your wishes could be answered, with the new fiber optics technology that is in the works.
A few scientists are working on this technology which could dramatically increase bandwidth and ease the clogging of Internet due to traffic. The new technology makes use of donut shaped laser light beams known as optical vortices - these beams twist like a tornado, when moving along a path-way, rather than move in a straight line.
Optical Vortices which are also known as orbital angular momentum or OAM beams were initially thought to be unstable in fibre, until an engineering professor at Boston University, Siddharth Ramachandran found a way to make this work. He describes the new technology in the US journal Science - conveying that the light beams can indeed be made stable in optical fibre.
"For several decades since optical fibres were deployed, the conventional assumption has been that OAM-carrying beams are inherently unstable in fibres," said Ramachandran .
"Our discovery, of design classes in which they are stable, has profound implications for a variety of scientific and technological fields that have exploited the unique properties of OAM-carrying light, including the use of such beams for enhancing data capacity in fibres," he added.
Optical communication system expert, Alan Willner form the University of Southern California is the co-author of the project. Ramachandran along with Willner demonstrated the technology, showing that it is possible to send as much as 1.6 terabits of data per second through one kilometer of optic fibre
OFS-Fitel, a fiber optics company in Denmark, and Tel Aviv University are other known collaborators for the project. The research has been funded by the Defense Advanced Research Projects Agency (DARPA).
