Scientists have succeeded to achieve a speed of 1.84 petabits per second. IT almost twice the estimated bandwidth of the entire global Internet (1 petabit/second). Thus, theoretically, all information on the Internet can be transmitted over this chip in less than a second.

what is known

Frequency comb optical chip technology is not new. And this isn’t the first recording he’s shown. As of 2020, engineers use it to achieve success after data transfer speed. A mathematical model shows that the traffic limit could reach 100 at some point. petabit/second – this is an incredible indicator.

The principle of operation of the chip is based on the application of an infrared laser beam to a frequency comb, which is a device that splits the basic beam into many separate waves. Each is converted into an encoded signal for data transmission with the help of polarization, amplitude and phase modulations. They are then combined into a beam again and transmitted through an optical fiber, and reverse decoding takes place at the receiver.

The latest version of the chip creates 233 separate waves, but as nanotechnology advances, their number can multiply. By transmitting many times more data in a single channel, it is also possible to create spatial copies of the base comb to “parallelize” the signal. Exactly The ability to scale the system almost to infinity is its main advantage Compared to existing analogues.

Unfortunately, nothing is known about the commercial application of this technology yet, but it is clear that its impact on the technology, the economy and the world in general should be huge.
