A Single Laser Transmitted a Second’s Worth of Internet Traffic in Record Time

Scientists continue to blow through data transmission records, with the fastest transmission of information between a laser and a single optical chip system now set at 1.8 petabits per second. That’s well in excess of the amount of traffic passing across the entire internet each second.

Here’s another comparison: the average broadband download speed in the US is 167 megabits per second. You need 1,000 megabits to get to a gigabit, and then 1 million gigabits to get up to 1 petabit.

No matter how you present it, 1.8 petabits is a serious amount of data to transmit in a second.

1 Million Gigabit Internet Speed Reached With a Single Chip and Laser

Researchers in Europe have developed an efficient way to deliver internet speeds at over 1 million gigabits per second through a single chip and laser system.

The experiment achieved a speed of 1.8 petabits per second, or nearly twice the amount of internet traffic the world transmits at the same rate. Amazingly, the feat was pulled off using only a single optical light source.

The research comes from a team at Technical University of Denmark and Chalmers University of Technology in Sweden. Last week, the group published a peer-reviewed paper (Opens in a new window) in Nature Photonics about the technology.

Toward Flawless Atom Optics

The engineering of so-called Floquet states leads to almost-perfect atom-optics elements for matter-wave interferometers—which could boost these devices’ ability to probe new physics.

Since Michelson and Morley’s famous experiment to detect the “luminiferous aether,” optical interferometry has offered valuable tools for studying fundamental physics. Nowadays, cutting-edge applications of the technique include its use as a high-precision ruler for detecting gravitational waves (see Focus: The Moon as a Gravitational-Wave Detector) and as a platform for quantum computing (see Viewpoint: Quantum Leap for Quantum Primacy). But as methods for cooling and controlling atoms have advanced, a new kind of interferometer has become available, in which light waves are replaced by matter waves [1]. Such devices can measure inertial forces with a sensitivity even greater than that of optical interferometers [2] and could reveal new physics beyond the standard model.

Hundred-Year-Old Shipwreck Emerges From River

The drought affecting the Mississippi River has revealed a watery secret – a shipwreck that’s over a hundred years old. The skeleton of the craft emerged in Baton Rouge this summer, thanks to low water levels. Dr. Chip McGimsey, archaeologist for the State of Louisiana, believes the ruins belong to the Brookhill Ferry, which sank in 1915. He says the wreck provides a unique way to explore the past, noting, “It makes history alive in a way that you don’t get any other way.”

New chip transmits a record breaking 1.84 petabits of data per second

It can download 230 million photographs in one second.

We all want more internet power and now we may just get it. A single computer chip has transmitted a record 1.84 petabits of data per second via a fiber-optic cable.


230 million photographs downloaded in one second

That amount exhibited enough bandwidth to download 230 million photographs in that time. The initiative was led by Asbjørn Arvad Jørgensen at the Technical University of Denmark in Copenhagen.
