Scientists Created It by Accident"},"content":{"rendered":"\n<h2 class=\"wp-block-heading\">An Accidental Discovery That Will Change the World<\/h2>\n\n\n\n<p>A few years ago, Michal Lipson&#8217;s team worked on improving LiDAR\u2014a technology that uses light waves to measure distance. They were designing high-power chips that would emit brighter light beams. However, they noticed something unusual during their experiments.<\/p>\n\n\n\n<p><em>&#8220;When we sent more and more energy through the chip, we noticed that something we called a <strong>frequency comb<\/strong> formed,&#8221; <\/em>says Andres Gil-Molina, one of the researchers, quoted in a Columbia University press release. A frequency comb is a special type of light that <strong>contains dozens of colors<\/strong> arranged next to each other in an ordered pattern\u2014a bit like a rainbow. Each color shines brightly, while the gaps between them remain dark.<\/p>\n\n\n\n<p>On a spectrogram, these bright frequencies look like the teeth of a comb. During research into this unusual light formation, it turned out that each &#8220;tooth&#8221; <strong>could function as a separate data transmission channel<\/strong>. This discovery, published in the <a href=\"https:\/\/www.nature.com\/articles\/s41566-025-01769-z\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">journal<\/a> <em>Nature Photonics<\/em>, could lead to a technological revolution.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">From Chaos to Precision<\/h2>\n\n\n\n<p>Previously, creating a <a href=\"https:\/\/holistic.news\/en\/how-are-diamonds-formed-co2-speeds-kimberlite\/\">powerful<\/a> frequency comb required large, expensive lasers and amplifiers. Lipson&#8217;s team showed how to achieve the same result on a single <a href=\"https:\/\/holistic.news\/en\/a-new-era-of-miniaturization-record-small-microchips\/\">chip<\/a>.<\/p>\n\n\n\n<p>The scientists asked themselves: what is the most powerful laser we can place on a chip? They ultimately chose a <strong>multi-mode laser diode<\/strong>\u2014a type used in medical devices and laser cutting tools. These devices <strong>produce enormous amounts of light<\/strong>, but the beam is chaotic, making it difficult to use for processes requiring precision.<\/p>\n\n\n\n<p><em>&#8220;We used a locking mechanism to clean up this powerful but very noisy light source,<\/em>&#8221; explains Gil-Molina. The method involves using silicon photonics to transform and clean up the laser&#8217;s output point. This creates a much cleaner, more stable beam.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The World&#8217;s Most Powerful Laser Fit on a Tiny Chip<\/h2>\n\n\n\n<p>After cleaning the light, the chip divides the single beam into dozens of evenly spaced colors. This creates the &#8220;frequency comb,&#8221; which combines the <strong>raw power of an industrial laser<\/strong> with the precision required for advanced communication. This is the <strong>high-power laser chip<\/strong> fit onto a record-small surface.<\/p>\n\n\n\n<p><em>&#8220;Data centers have created a huge demand for powerful and efficient light sources that contain many wavelengths,&#8221;<\/em> emphasizes Gil-Molina. <em>&#8220;The <a href=\"https:\/\/holistic.news\/en\/smart-triage-wristband-polish-students-dyson-final\/\">technology<\/a> we developed converts a very powerful laser into dozens of clean, high-power channels on a chip. You can <strong>replace racks of individual lasers with one compact device<\/strong>, lowering costs, saving space, and opening the door to much faster, more energy-efficient systems.&#8221;<\/em><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What Will Be the Effects of the Extraordinary Invention?<\/h3>\n\n\n\n<p>Beyond data centers, the chips developed by the researchers could also enable the creation of portable spectrometers. They can also be applied in ultra-precise optical clocks, compact quantum devices, and even the advanced LiDAR systems, where the story of this extraordinary accidental discovery began.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><em>Read this article in Polish: <\/em><a href=\"https:\/\/holistic.news\/najmocniejszy-laser-swiata-zmieszczony-na-chipie-przypadkowe-odkrycia-naukowe\/\">Chip z&nbsp;laserem o&nbsp;mocy fabryki.
