Nvidia's $2B Bet on US Optics

This partnership directly targets the physical constraints of scaling AI, as traditional copper interconnects fail to meet the bandwidth density and power efficiency required by massive GPU clusters. The move to optical interconnects is critical for handling the massive east-west traffic patterns inside next-generation AI systems without creating data bottlenecks. The investment specifically supports the expansion of Lumentum's San Jose, CA semiconductor facility, which designs and manufactures the ultra-high-power (UHP) indium phosphide lasers essential for co-packaged optics (CPO) platforms. Lumentum is a dominant supplier of the Electro-absorption Modulated Lasers (EMLs) needed for the 1.6T transceivers being deployed in the newest AI data centers. This isn't an isolated move; Nvidia also announced a similar $2 billion investment in optical components supplier Coherent. The parallel deals represent a $4 billion strategic push by Nvidia to vertically integrate key parts of its supply chain, securing the critical photonics needed for its ambitious "AI Factories" roadmap. Nvidia's $2 billion investment gives it 2,876,415 shares of Series A Convertible Preferred Stock in Lumentum. The agreement goes beyond equity, including a multi-billion dollar purchase commitment for Lumentum's products and guarantees Nvidia access to future manufacturing capacity. The deal provides immense revenue visibility for Lumentum (NASDAQ: LITE), which already reported a 65.5% year-over-year revenue surge to $665.5 million in its last fiscal quarter. The company holds a backlog of over $400 million for its Optical Circuit Switch (OCS) products, a technology designed to improve network performance in AI clusters. For the Bay Area, this investment will create a significant number of high-skilled engineering and
