And only carried by the light from one optical source. The light source is a custom-designed optical chip, which can use the light from a single infrared laser to create a rainbow spectrum of many colors, i.e., many frequencies. Thus, the one frequency (color) of a single laser can be multiplied into hundreds of frequencies (colors) in a single chip.<\/p>\n<p>All the colors are fixed at a specific frequency distance from each other\u2014just like the teeth on a comb\u2014which is why it is called a frequency comb. Each color (or frequency) can then be isolated and used to imprint data. The frequencies can then be reassembled and sent over an optical fiber, thus transmitting data. Even a huge volume of data, as the researchers have discovered.<\/p>\n<p><b>One single laser can replace thousands<\/b><\/p>\n<p>The experimental demonstration showed that a single chip could easily carry 1.8 Pbit\/s, which\u2014with contemporary state-of-the-art commercial equipment\u2014would otherwise require more than 1,000 lasers.<\/p>\n<p>Victor Torres Company, professor at Chalmers University of Technology, is head of the research group that has developed and manufactured the chip.<\/p>\n<p>&#8220;What is special about this chip is that it produces a frequency comb with ideal characteristics for fiber-optical communications\u2014it has high optical power and covers a broad bandwidth within the spectral region that is interesting for advanced optical communications,&#8221; says Victor Torres Company.<\/p>\n<p>Interestingly enough, the chip was not optimized for this particular <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>lication.<\/p>\n<p>&#8220;In fact, some of the characteristic parameters were achieved by coincidence and not by design,&#8221; says Victor Torres Company. &#8220;However, with efforts in my team, we are now capable to reverse engineer the process and achieve with high reproducibility microcombs for target applications in telecommunications.&#8221;<\/p>\n<p><b>Enormous potential for scaling<\/b><\/p>\n<p>In addition, the researchers created a computational model to examine theoretically the fundamental potential for data transmission with a single chip identical to the one used in the experiment. The calculations showed enormous potential for scaling up the solution.<\/p>\n<p>Professor Leif Katsuo Oxenl\u00f8we, Head of the Center of Excellence for Silicon Photonics for Optical Communications (SPOC) at DTU, says:<\/p>\n<p>&#8220;Our calculations show that\u2014with the single chip made by Chalmers University of Technology, and a single laser\u2014we will be able to transmit up to 100 Pbit\/s. The reason for this is that our solution is scalable\u2014both in terms of creating many frequencies and in terms of splitting the frequency comb into many spatial copies and then optically amplifying them, and using them as parallel sources with which we can transmit data. Although the comb copies must be amplified, we do not lose the qualities of the comb, which we utilize for spectrally efficient data transmission.&#8221;<\/p>\n<p><b>This is how you pack light with data<\/b><\/p>\n<p>Packing light with data is known as modulation. Here, the wave properties of light are utilized such as:<\/p>\n<ul>\n<li>Amplitude (the height\/strength of the waves)<\/li>\n<li>Phase (the &#8220;rhythm&#8221; of the waves, where it is possible to make a shift so that a wave arrives either a little earlier or a little later than expected)<\/li>\n<li>Polarization (the directions in which the waves spread).<\/li>\n<\/ul>\n<p>By changing these properties, you create signals. The signals can be translated into either ones or zeros\u2014and thus utilized as data signals.<\/p>\n<p><b>Reduces Internet power consumption<\/b><\/p>\n<p>The researchers&#8217; solution bodes well for the future power consumption of the Internet.<\/p>\n<p>&#8220;In other words, our solution provides a potential for replacing hundreds of thousands of the lasers located at Internet hubs and data centers, all of which guzzle power and generate heat. We have an opportunity to contribute to achieving an Internet that leaves a smaller climate footprint,&#8221; says Leif Katsuo Oxenl\u00f8we.<\/p>\n<p>Even though the researchers have broken the petabit barrier for a single laser source and a single chip in their demonstration, there is still some development work ahead before the solution can be implemented in our current communication systems, according to Leif Katsuo Oxenl\u00f8we.<\/p>\n<p>&#8220;All over the world, work is being done to integrate the laser source in the optical chip, and we&#8217;re working on that as well. The more components we can integrate in the chip, the more efficient the whole transmitter will be, i.e., laser, comb-creating chip, data modulators, and any amplifier elements. It will be an extremely efficient optical transmitter of data signals,&#8221; says Leif Katsuo Oxenl\u00f8we.<\/p>\n<p>The research is published in <i>Nature Photonics<\/i>.<\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            <a rel=\"nofollow noopener\" target=\"_blank\" class=\"text-medium text-info mt-2 d-inline-block\" href=\"https:\/\/techxplore.com\/news\/2022-10-petabits-fiber-optic-cable-distance-km.html\">Sending 1.84 petabits of data per second via a fiber-optic cable over a distance of 7.9 km<\/a>\n                                        <\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                A.
