  • this video that you're watching right now is data that's being transferred to you through a wire, which is then decoded, making it into something viewable on your device on That's the Internet out of being bada boom.

  • No, I'm just getting It's a lot more complicated than that.

  • But part of what we call the Internet is information that travels through wires from servers, satellite's data centers or other computers to your personal router.

  • These wires are more formally known as fiber optic cable.

  • And did you notice the important part of that name fiber optic cable?

  • That's because all that data the information being transferred to you as you request it from your Web browser on your desktop or the banking app on your phone physically travels through the wires in the form of light pulses of light.

  • Our son from the data's point of origin through the cable photons bouncing around inside that cable travel to the other end where there's some kind of receiver like a photo die owed or a photo electric cell.

  • And this device is what translates those packets of light in there, even pattern back into electrical information that your computer can then understand and present to you as the information you asked for, like a Web page That's crazy, right?

  • Well, it's about to get even crazier.

  • New research has just demonstrated the feasibility of the world's first nano photonic device.

  • See, in most standard systems, we currently only use a fraction of lights capacity to transmit data, and this is because we haven't previously had the technology to decode anything else.

  • But new efforts are making use of light beyond the visible spectrum, like ultraviolet waves.

  • And in this version of data transmission, the light is not just photons pinging around, reflecting their way down the inside of the cable the lightwaves, both visible and not obsolete in a particular way, to form a twisted pattern also known as orbital, angular momentum or twisted light.

  • Because twisted light is made up of more modes of light, that light is able to carry more information, in fact, because the light traveling through the fiber is made up of different kinds of twists that can even overlap with one another, each carrying a different data stream all at the same time without interfering with each other.

  • But we have to have something at the other end of that fibre that can then be code all that packed in information, right?

  • And this brand new nano photonic chip can do exactly that.

  • Using something called ultra thin complimentary Metal oxides Semiconductor Technology, which is quite a mouthful, the team has successfully demonstrated what they call compact, high precision, angular momentum.

  • Nana Metrology, man, that vocab is something else.

  • I liked it when we were just calling a twisted light.

  • Basically, the technology we used to have to decode even a smidgen of that twisted light data was the size of a table.

  • And now it's the size of an ultra thin wafer that fits onto the end of an optical fiber.

  • Bring us a little closer to the use of twisted light in the real world, because the thing is, we don't just use fiber optic cable for accessing a bountiful power of the Internet.

  • We also now use it to carry our phone conversations to broadcast TV and even in medical applications to measure vital patient statistics like cell pH or the presence of medicine or toxins in the bloodstream, vastly enhancing the amount of data that can be sent through fiber optic cable and then importantly, processed and translated at never before seen speeds and in a usable way could transform our whole informational world.

  • Chances are, though, this won't be used to bring the consumer that much more computing power.

  • It's more applicable in cases like finding better ways to communicate with vehicles in space or potentially providing a way for us to process and use the information that would hypothetically come from quantum computers, which would be leaps away from the complexity and size of the data that we work within our current computing systems.

  • What can we say the future looks bright, twisted, right?

  • Fun fact.

  • Reportedly, 99% of international data passes through wires at the bottom of the ocean called submarine communications cables thousands of miles long.

  • Thanks for always coming back to secret for your breaking science and tech news on.

  • Don't forget to subscribe to be the first to know how this technology it goes into action for more like this.
