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

If you’re attending DAC 2026, join the talk on July 29th by Xuejue Cathy Huang, Principal Architect, that will describe a co-simulation and verification methodology for next-generation co-packaged optics systems. https://lnkd.in/grr2K-aF

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

The future of AI scale-up is optical. With global fiber supply already strained, how you transition to photonic interconnects matters. Lightmatter's industry-leading Passage BiDi architecture, built for NVIDIA's NVLink Fusion ecosystem, was designed for exactly this constraint. By enabling simultaneous bidirectional signaling over the same optical paths, our BiDi links cut required optical fibers and connectors in half. “Integrating Lightmatter’s advanced photonic engines into the NVLink Fusion ecosystem provides our partners and hyperscale customers with more choice and flexibility to build specialized, energy-efficient AI infrastructure at unprecedented scale.” –Ashish Karandikar, Vice President of Engineering, NVIDIA In addition, other optical approaches communicate at chip perimeters. Lightmatter's 3D optical engines stack electronic ICs and processors directly on a silicon photonics engine to deliver the highest interconnect bandwidth and radix available for hyperscale AI infrastructure.

In the latest EE Times podcast "AI With Sally," our Founder and CEO Nicholas Harris spoke with senior reporter Sally Ward-Foxton about photonics in the data center. In the episode, Harris explains why AI has shifted from a compute-bound problem to an interconnect- and memory-bound one, how Lightmatter evolved from pursuing photonic processors to building optical networking technology, and why the company's new integrated laser platform represents the next step toward scaling AI infrastructure beyond what copper can support.
