An international team of researchers has reportedly set a data transmission record using just a single laser and optical chip to transmit more than 1 Pbit/s. The researchers, from the Technical University of Denmark (DTU) and Chalmers University of Technology in Sweden, transmitted data at 1.8 Pbit/s, corresponding to double the total global internet traffic.
The demonstrated data transmission method used significantly less power than conventional approaches to data transmission and can help reduce the internet’s climate footprint, according to the team.
The light source in the team’s experiment was a custom-designed, frequency comb-producing optical chip; the chip used light from a single infrared laser to create a...
