China’s grip on indium phosphide is tightening pressure on the CPO supply chain

Indium phosphide has moved to the center of the optical supply chain as AI data center buildouts drive demand for high-speed optical modules and co-packaged optics, or CPO. The article argues that China now holds critical leverage across all three major steps of the indium phosphide chain: primary indium smelting, indium refining, and wafer manufacturing. That position has become more consequential after Beijing expanded export controls from indium phosphide products to upstream indium itself. The report details how pressure is building across the industry. Lumentum’s CEO said earlier this month that the shortage in indium phosphide is even more severe than in memory, while Nokia has moved to secure production by acquiring facilities tied to indium phosphide manufacturing. Coherent, a major supplier of indium phosphide laser products used in Nvidia’s CPO systems, is also highlighted as scrambling to secure supply as customers push for more capacity. At the same time, Chinese companies including Yunnan Germanium and Zhuzhou Keneng are seeing stronger orders and making progress on larger wafers and higher-purity indium products. Still, the article says two constraints remain unresolved: customer qualification cycles and capacity expansion. Even with Chinese suppliers gaining ground, the gap between projected global demand and effective supply remains large heading into 2026.
