New record set: one chip was able to transmit all Internet traffic in one second

The new photonic chip was made by Asbjørn Arvad Jørgensen of the Technical University of Denmark in Copenhagen and his colleagues. This technology makes it possible to build optical components on PC chips to divide a data stream into thousands of separate channels and transmit them all at once without optical interference in this case.

The established record allowed to use enough bandwidth to download 230 million photos per secondthat is, more traffic than that which travels across the entire Internet network in the same amount of time.


To achieve this the team started splitting the data stream into 37 sections, each of which was sent along a separate core of the 7.9 km long fiber optic cable.

Subsequently, each of these channels was split into 223 blocks of data that existed in individual sections of the electromagnetic spectrum.

This set of evenly spaced light peaks, in the frequency spectrum, allowed the transmission of data with different colors at the same time without interfering with each other, thus enormously increasing the capacity of each core.

From a general point of view and with much more cumbersome equipment they have been achieved data transfer rates up to 10.66 petabits per secondHowever, the record established by this research used a single computer chip as a light source.

The technology could enable the creation of simple single chips that can send far more data than existing models, reducing energy costs and increasing bandwidth.


Another element of interest, but also an obstacle at the moment, is that the amount of data sent during the experiment was so vast that there is no computer capable of providing or receiving so much information in the time interval considered.

In the experiments, the team sent dummy data across all channels, testing the output on one channel at a time. At the end it was verified that what was sent was recovered intact.


It is an incredibly large amount of data that we are sending, on less than a square millimeter “, he has declared Jørgensen. “This just shows that we can go much further than we are today with Internet connections.”

The chip needs a single laser split into many light frequencies, as well as separate devices to encode the data in each of the output streams. Jørgensen said these devices could be integrated into the chip itself, making the size of the whole apparatus similar to a matchbox.
