An accidental discovery turned one laser into a rainbow of high-speed data
Researchers accidentally discovered that a single infrared laser could be split into a rainbow of frequencies, creating a microcomb capable of transmitting the entire world’s internet traffic through a single fiber optic chip.
While experimenting with optical fibers in 2022, scientists in Denmark and Sweden achieved a record-breaking data transfer rate of 1.8 petabits per second. This massive speed was made possible by a custom-designed optical chip that splits a single laser into hundreds of different frequencies.
