BitcoinWorld Optical processors breakthrough: Neurophos secures $110M to revolutionize AI inferencing with metamaterial technology AUSTIN, Texas — In a significant development for artificial intelligence infrastructure, photonics startup Neurophos has secured $110 million in Series A funding to commercialize optical processors that could dramatically reduce the energy consumption of AI inferencing. The company’s technology, derived from metamaterials research originally developed for electromagnetic cloaking, promises processing speeds and efficiency gains that challenge Nvidia’s dominance in AI hardware. From invisibility research to optical computing revolution The journey from electromagnetic cloaking to optical processors represents a remarkable evolution in materials science. Two decades ago, Duke University professor David R. Smith pioneered metamaterials research that demonstrated limited invisibility effects at microwave frequencies. Today, that same fundamental research has spawned Neurophos, a startup developing what it calls “metasurface modulators” for optical computing. These modulators function as tensor core processors specifically designed for matrix vector multiplication—the mathematical operation at the heart of AI inferencing. Unlike traditional silicon-based GPUs and TPUs that use electrical signals, Neurophos’s optical processing units (OPUs) manipulate light to perform calculations. This approach offers several theoretical advantages, including reduced heat generation and faster signal propagation. The $110 million funding round and strategic investors Neurophos’s recent funding round attracted significant attention from major technology investors. Gates Frontier, Bill Gates’s venture firm, led the investment, with participation from Microsoft’s M12 fund, Carbon Direct, Aramco Ventures, Bosch Ventures, Tectonic Ventures, and Space Capital. This diverse investor group reflects broad industry recognition of the potential impact of optical computing on AI infrastructure. Dr. Marc Tremblay, corporate vice president and technical fellow of core AI infrastructure at Microsoft, emphasized the technology’s importance in a statement: “Modern AI inference demands monumental amounts of power and compute. We need a breakthrough in compute on par with the leaps we’ve seen in AI models themselves, which is what Neurophos’s technology and high-talent density team is developing.” Technical specifications and competitive advantages Neurophos claims its optical processors achieve remarkable performance metrics compared to current market leaders. According to company data, their chip operates at 56 GHz, delivering 235 Peta Operations Per Second (POPS) while consuming just 675 watts. In contrast, Nvidia’s B200 AI GPU reportedly delivers 9 POPS at 1,000 watts—a significant efficiency gap.

Traditional optical transistors face significant size limitations, but Neurophos claims its metasurface modulators are approximately 10,000 times smaller than conventional optical components. This miniaturization enables the company to fit thousands of units on a single chip, dramatically increasing computational density. Solving photonic computing’s traditional challenges Photonic computing has long promised advantages over silicon-based electronics, but several persistent challenges have limited commercial adoption. Optical components typically require: Larger physical footprints than silicon transistors Complex data conversion between optical and electronic domains Specialized manufacturing processes incompatible with existing foundries Neurophos addresses these issues through its metasurface technology. The company’s chips can reportedly be manufactured using standard silicon foundry materials, tools, and processes. Additionally, the reduced size of their optical components minimizes the need for frequent data conversion between domains, improving overall efficiency. Dr. Patrick Bowen, CEO and co-founder of Neurophos, explained the technical approach: “When you shrink the optical transistor, you can do way more math in the optics domain before you have to do that conversion back to the electronics domain. If you want to go fast, you have to solve the energy efficiency problem first.” Market timing and competitive landscape Neurophos enters a rapidly evolving AI hardware market dominated by Nvidia, which currently supplies the majority of GPUs powering AI training and inference. However, the company positions its technology as complementary rather than directly competitive, focusing specifically on inference workloads where energy efficiency matters most. The startup acknowledges it faces competition from other photonics companies, though some competitors like Lightmatter have shifted focus to optical interconnects rather than processing units. Neurophos expects its first chips to reach the market by mid-2028, giving the company several years to refine its technology while the AI hardware market continues to expand. Bowen remains confident about the company’s competitive position: “What everyone else is doing, including Nvidia, in terms of the fundamental physics of the silicon, it’s really evolutionary rather than revolutionary. Even if we chart out Nvidia’s improvement in architecture over the years, by the time we come out in 2028, we still have massive advantages.” The environmental imperative for efficient AI The timing of Neurophos’s technology development coincides with growing concerns about AI’s environmental impact. Recent studies indicate that data center energy consumption could double by 2026, driven largely by AI workloads. More efficient processing hardware represents a critical component of sustainable AI development. Neurophos’s optical processors could significantly reduce the carbon footprint of AI inference, which constitutes the majority of computational workload for deployed AI systems. The company claims its technology offers 50x improvements in both energy efficiency and raw speed compared to Nvidia’s current Blackwell architecture. Implementation roadmap and commercial strategy The $110 million funding will support several key initiatives over the coming years. Neurophos plans to develop its first integrated photonic compute system, including datacenter-ready OPU modules, a complete software stack, and early-access developer hardware. The company is also expanding its physical presence with a new engineering site in San Francisco and an expanded headquarters in Austin, Texas. Neurophos has already signed multiple customers, though the company has not disclosed their identities. Microsoft is reportedly “looking very closely” at the startup’s products, suggesting potential integration with Azure’s AI infrastructure. The company’s technology could eventually benefit various applications, including: Large language model inference for chatbots and content generation Computer vision systems for autonomous vehicles and surveillance Scientific computing requiring massive matrix operations Edge AI applications where power constraints are critical Conclusion Neurophos’s $110 million funding round represents a significant vote of confidence in optical computing’s potential to transform AI infrastructure. The company’s metamaterial-based optical processors promise unprecedented efficiency gains for AI inferencing, addressing both performance demands and environmental concerns. While commercial availability remains several years away, the technology could eventually challenge silicon’s dominance in high-performance computing. As AI models grow increasingly complex and energy-intensive, innovations like Neurophos’s optical processors may prove essential for sustainable AI development.
