en.Wedoany.com Reported - Photonic supercomputing company Lightmatter officially announced on April 27 the appointment of Roy Kim as Vice President of Products, who will be fully responsible for the company’s global product strategy, product management, and market roadmap execution. With over 15 years of product leadership experience in AI infrastructure, Kim previously held key product management roles at NVIDIA, AMD, and Google. Founder and CEO Nick Harris stated, “Co-packaged optics is transitioning from proof of concept to production. Over the next 18 to 24 months, the products and partnerships we deliver will define the AI data centers of the next decade.”
Kim joins Lightmatter at a critical juncture as the company transitions from technology validation to commercial-scale deployment. Prior to joining Lightmatter, Kim served as Head of AI Infrastructure Product Management at Google since 2021, leading the design and deployment of hyperscale AI system architectures. Earlier, he managed Data Center GPU products at AMD and spent nearly a decade at NVIDIA, focusing on the development and commercialization of AI and high-performance computing products. Lightmatter stated that Kim’s composite experience in hyperscale system architecture, silicon wafer manufacturing processes, and deployment workflows will be a key driver in bringing photonic interconnect technology from the lab to mass production.
Founded in 2017 in Boston by Nicholas Harris, Lightmatter focuses on using silicon photonics to solve bandwidth and power consumption bottlenecks in inter-chip connectivity for AI data centers. In October 2024, the company closed a $400 million Series D funding round at a valuation of $4.4 billion, with cumulative funding reaching approximately $850 million. Kim will take full responsibility for driving the strategic development of Lightmatter’s two core product lines: the Passage photonic interconnect platform and the Guide VLSP optical engine.
The Passage photonic interconnect platform is Lightmatter's core technology product. In March 2026, the company launched the Passage L20 general-purpose optical engine, which provides 6.4Tbps of bidirectional optical bandwidth with 32 optical ports and a data rate of 200Gbps per channel, designed for near-package optics and on-board optics deployment scenarios. The Passage L20 supports the emerging XPO form factor and integrates seamlessly with next-generation XPUs and switches. That same month, Lightmatter also introduced the vClick Optics detachable fiber array unit, the industry's first detachable fiber array designed for co-packaged optics architectures. This technology reduces insertion loss to below 1.5dB, supports high-bandwidth dense wavelength division multiplexing, is compatible with advanced packaging processes, and offers field maintainability, directly addressing the manufacturing and maintenance pain points that have hindered CPO volume production.
The Guide VLSP optical engine is another core pillar of Lightmatter's photonic product portfolio. In January 2026, Lightmatter launched the Guide VLSP optical engine, which supports transmission rates up to 51.2Tbps per laser module and has already begun providing samples to customers. This technology integrates high-density laser sources into standardized modules, offering a low-power, high-bandwidth light source solution for large-scale AI clusters.
Lightmatter is accelerating the deployment of CPO solutions through deep collaboration with the global semiconductor industry chain. In January 2026, Lightmatter and Global Unichip Corporation (GUC) announced a partnership to combine Passage photonic interconnect technology with GUC's ASIC design services and advanced packaging capabilities, specifically targeting connectivity bottlenecks in AI and HPC workloads. Nick Harris remarked at the time, “Computing architecture is undergoing a qualitative shift. As single-chip performance improvements slow, interconnect architecture has become the core of computing power.” In March 2026, Lightmatter joined the XPO MSA Board as a founding member to promote industry standardization for high-density optical interconnects in AI data centers. Nick Harris noted that the rapid growth of AI infrastructure is forcing entire data centers to rethink interconnect architectures, and joining XPO MSA allows Lightmatter to bring its high-bandwidth-density photonic technology to a broader industry collaboration platform.
Lightmatter's current ecosystem partners include semiconductor giants such as TSMC and ASE Technology, as well as several leading global cloud service providers. The company plans to leverage Kim's deep experience in hyperscale architecture, partner ecosystem development, and product scaling to drive the widespread adoption of photonic interconnect technology in AI data centers.
