Summary

Coherent has broken ground on an expanded 6-inch indium phosphide (InP) fabrication plant in Sherman, Texas, positioning it as a core site for global AI infrastructure. This expansion, backed by NVIDIA's \$2 billion investment in March 2026, aims to significantly scale the production of specialized InP wafers. These wafers are vital for high-speed optical interconnects, enabling data transfer at light speed between chips, servers, and data centers in advanced AI systems like NVIDIA's Vera Rubin Ultra NVL576 architecture. The project, which received a \$50 million federal CHIPS Act grant and \$17 million in regional support, is expected to create over 1,000 jobs, including more than 550 direct advanced manufacturing roles. The expansion will double manufacturing space and quadruple wafer production capacity, strengthening the US supply chain for AI technologies.

Key takeaway

For CTOs and AI infrastructure architects planning future data center expansions, you must prioritize optical interconnects over traditional copper cabling. As AI factories scale to connect millions of GPUs, silicon photonics become essential. Indium phosphide-based solutions are crucial for achieving necessary speed, energy efficiency, and physical distance. Your strategic investments should include partnerships with specialized semiconductor manufacturers to secure the supply chain for these critical AI-enabling technologies.
