Enlightra exits stealth with $15M to power energy-efficient AI data centre lasers
Enlightra, a deeptech startup, has emerged from stealth mode with $15 million in funding to develop advanced chip-scale multiwavelength lasers. These lasers are designed to improve data transmission in AI infrastructure, addressing the limitations of current copper-based systems. The investment reflects growing interest in technologies that can meet the increasing demands of AI training and data center operations. Enlightra's lasers consolidate multiple discrete lasers into a single integrated source, improving efficiency. This approach reduces power consumption, cost, and physical footprint. The technology supports a shift from copper wiring to compact optical links, with each wavelength acting as an independent data channel. The company is developing 8- and 16-channel lasers, with pilot production planned for 2027. The implications of Enlightra's technology extend beyond AI clusters. Its scalable comb-laser platform could power future optical links across data centers, subsea cables, and chip-to-memory interconnects. This advancement could significantly impact various sectors reliant on high-speed data transfer, including quantum and space-based communications. The funding will be used to improve data transfer speed and energy efficiency.
