Most high-performance computing systems still rely heavily on copper wiring to connect GPUs and accelerators, a technology increasingly seen as a bottleneck for both performance and sustainability. Enlightra aims to replace these electrical links with compact optical connections that deliver significantly higher bandwidth while consuming far less energy.<\/p>\n\n\n\n<p>Founded in 2022, Enlightra develops multi-color, or \u201ccomb-laser,\u201d technology that generates multiple optical wavelengths from a single chip-scale source. Each wavelength functions as an independent data channel, enabling dozens of high-bandwidth links to be transmitted simultaneously over optical fiber. According to the company, this approach reduces power consumption, cost and physical footprint compared with systems based on multiple discrete lasers.<\/p>\n\n\n\n<p>The USD 15 million funding round has enabled Enlightra to design, build and demonstrate its laser technology, with initial 8- and 16-channel devices already meeting customer specifications for AI chip interconnects. The company reports error-free data transmission at target speeds and power levels, with pilot production planned for 2027. Investors include <a href=\"https:\/\/www.ycombinator.com\/\">Y Combinator<\/a>, <a href=\"https:\/\/runacap.com\/\">Runa Capital<\/a>, <a href=\"https:\/\/www.pegasustechventures.com\/\">Pegasus Tech Ventures<\/a>, <a href=\"https:\/\/www.protocol.ai\/\">Protocol Labs<\/a>, Halo Labs, <a href=\"https:\/\/asymmetry.vc\/\">Asymmetry Ventures<\/a> and <a href=\"https:\/\/www.trac.vc\/\">TRAC VC<\/a>.<\/p>\n\n\n\n<p>\u201cAI infrastructure is hitting the physical and energy limits of copper,\u201d said Maxim Karpov, co-founder and co-CEO of Enlightra. \u201cBy using light as the backbone of GPU communication, we can decouple performance growth from energy consumption.\u201d<\/p>\n\n\n\n<p>Built using industry-standard silicon photonics fabrication processes, Enlightra\u2019s lasers are designed for large-scale manufacturing, opening the door to deployment across global data centers. While AI clusters are the initial focus, the company sees broader applications in data center networking, subsea communications, chip-to-memory interconnects, and longer-term use cases such as quantum and space-based communications.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Enlightra has secured USD 15 million to develop chip-scale, multiwavelength laser technology designed to improve
