Yunnan Germanium Investing ¥189M in Indium Phosphide Wafers for Optical Communications

Yunnan Germanium (云南锗业) has announced a ¥189 million ($26M) investment in a high-quality indium phosphide (InP) single crystal wafer project to meet surging demand from the optical communications market.

Project Details

• Total investment: ¥189 million
• Executed by: Subsidiary Yunnan Xinyao
• Target capacity: 450,000 wafers annually (4-inch equivalent)
• Method: Capacity expansion on existing production base

Market Driver

The investment responds to rapid growth in the optical communications market:

• High-speed optical modules entering mass deployment
• Downstream demand for InP wafers continuously expanding
• Higher requirements for wafer size and quality
• 5G/6G, data centers, AI: All driving optical communication demand

Why Indium Phosphide?

InP wafers are essential for:

• Laser diodes: The backbone of optical communications
• Photodetectors: Converting light signals to electrical signals
• High-frequency electronics: 5G/6G infrastructure
• Silicon photonics: Integration with CMOS processes

Strategic Significance

This investment highlights a critical trend: AI data center demand is creating massive growth in optical communications infrastructure. As AI training clusters require ever-faster interconnects, the demand for high-quality InP wafers is set to accelerate — making this a strategic supply chain investment.
