Lightmatter

Our CEO Nicholas Harris will deliver a talk titled “Photonics Is the Future of Computing” at UC Berkeley on Saturday, August 1 at 10:15 AM PT as part of the Agentic AI Summit 2026 (Compass session 1), hosted by Berkeley RDI and Responsible Decentralized Intelligence Foundation. The event brings together leaders to explore, discuss, and collaboratively shape the future of AI and Agentic AI. Register to join the free livestream: https://lnkd.in/e6bbBFXE

Happy #NationalInternDay to the incredible cohort shaping the future of photonic computing at Lightmatter! When we welcomed our 31 summer interns, we promised they wouldn't be watching from the sidelines. True to our word, we’ve handed them the keys—placing immense trust in their talents and giving them the opportunity to work on high-impact projects. To our summer cohort: thank you for your curiosity, relentless drive, and the bold fresh perspectives you bring to our mission every day. Keep pushing boundaries!

Interoperability is how networks and ecosystems scale. Join us at OIForum’s #ECOC26 showcase in September, where 40 participating companies will demonstrate interoperable optical systems, 448G & 224G common electrical I/O (CEI), CMIS, co-packaging, energy efficient interfaces and more. Visit booth #2126. Learn more: https://lnkd.in/ePRJttpR #NextGenNetworks #Interop

If you missed the recent LightCounting Market Research virtual conference focused on co-packaged optics and near-packaged optics, the replay is available now. Hear Steve Klinger and other industry experts discuss the latest progress in CPO and NPO standardization and ecosystem development, system development and deployment.

Thank you to Societe Generale Bernstein for hosting us at "The Now Frontier: AI and Robotics" conference in Palo Alto this week, and to Stacy Rasgon for moderating an engaging fireside chat with our Founder and CEO, Nicholas Harris, alongside the CEOs of d-Matrix, Mythic, and EnCharge AI. It’s an exciting time for the industry. With insatiable AI demand, the field of chips and data centers is wide open for breakthrough innovation. Nick shared how Lightmatter’s Passage photonic interconnects and Guide lasers are unlocking the next 10x speedup for AI workloads—from training to decode. We’re just getting started! Follow Lightmatter to see where our photonic innovations take AI next.

Moore's Law and its successor—silicon area scaling—are hitting a wall. The future of computing is defined by the quality of connectivity between chips. In a timely article from Tom's Hardware, our CEO Nicholas Harris breaks down why optical interconnects have become the critical battleground in AI infrastructure: • Copper has hit physical bandwidth/reach limits • Optics path: Pluggables → NPO → CPO → Interposers (boosting speed & efficiency) • 2027-2028 are pivotal as NPO is proving ground and CPO ships at scale • Lasers are the next bottleneck—and 50% of the market opportunity Lightmatter is scaling its solutions through open standards, including in Open Compute Project Foundation, and through NVIDIA's NVLink Fusion ecosystem as an optical interconnect partner. #photonics #optics #artificialintelligence https://lnkd.in/gmiTmTX3

Lightmatter was just named one of the 10 coolest semiconductor startups of 2026 by CRN: Computer Reseller News. We're proud to be recognized alongside other innovators pushing the boundaries of AI infrastructure and tech hardware — see page 7 for our overview. Thanks Mark Haranas for the spotlight. https://lnkd.in/g6Pmhp6S Nicholas Harris

Lightmatter is in the spotlight in IEEE Spectrum! The latest feature explores a critical turning point in data center architecture as the industry rapidly transitions to optical networking inside the rack. In the article, our VP of Product, Roy Kim, breaks down how Lightmatter is solving the copper bottleneck. While traditional methods rely on interfacing optical chiplets to the edges of processors, we’re 3D-integrating silicon photonics as the interconnect fabric inside the package. With Passage photonic interposers, we allow processors to stack vertically—bypassing the edge-routing chokepoints that limit communications bandwidth. The packaging hurdles of the past have been cleared. Today, scale-up networking also requires dense, high-performance external laser solutions. Lightmatter is tackling this head-on by integrating lasers directly onto silicon, driving unprecedented bandwidth density and scalability. Thank you to IEEE Spectrum and Knvul Sheikh for highlighting how we are rewriting the rules of chip connectivity to power the future of AI. Read the full article: https://lnkd.in/gXm_R7pp
