A research team at the University of Southern California have successfully developed a data transmission technology capable of transferring large amounts of data with a capacity equivalent to 70 pieces DVD in 1 sec.
Led by Alan Willner, a professor of electrical engineering at USC, the team was able to improve the technology of twisted light current to reach the speed of 2.56 terabits/sec, with a distance of approximately 1.5 meters.
“We did not create a method of twisted light, but took the concept to boost the speed up to reach the level of terabit-per-second. By using the media of light, you will be able to do various things that can not be done with electric media. And that’s the beauty of light, a set of photons that can be manipulated in various ways at very high speeds. “
Wilner said that the implementation for the technology developed by this team is to manipulate the ‘phase holograms’ to break the 8 kinds of light into a spectrum similar to the DNA helix. The resulting hologram is then able to be used to load data in the form of bits (binary digits consisting of a series of numbers 0 and 1) are independent of each spectrum in a very short time.
According to the research team, this technology has the potential to be used in satellite communications, high speed, short terrestrial links or even super-long fiber optic cable.
