By splitting a single laser beam into different wavelengths of light, engineers were able to transmit data at nearly twice the rate of the world’s combined Internet traffic per second.
This mind-boggling achievement was achieved with just a laser and a single optical chip.
Engineer at Chalmers Institute of Technology and College of Technology. Danish scientists shot infrared lasers through splitters called “frequency combs” that split the light into many different colors.
Each color or frequency can carry data by modulating amplitude, phase and polarization. The total amount of data that can be encoded is 1.8 petabits per second, or 1.8 million gigabytes. 800,000 more than the average global bandwidth of the entire Internet.
A single optical chip designed by Chalmers could easily carry 1.8 Pbit/s. Using modern state-of-the-art commercial equipment, this would otherwise require over 1,000 lasers.
The work of Leif Katsuo Oxenløwe et al. also showed The technology should be scalable.
“Our calculations show that one chip and one laser can transmit up to 100 Pbit/s.”
“The reason is that our solution is scalable. We can create many frequencies and split the frequency comb into many spatial copies and then optically amplify them, and we can transmit data Both in terms of its use as a parallel source, Said Professor Oxenløwe added that this bodes well for emissions targets.
“In other words, our solution offers the potential to replace hundreds of thousands of lasers deployed in internet hubs and data centers, all of which consume power and generate heat. We have an opportunity to contribute to the realization of an internet with a smaller climate footprint.”
May this year, New Atlas Report A transmission record of 1.04 Pbits/s was made in Japan with a different technology. Oxenløwe said there are people all over the world working to achieve this kind of internet capacity.
