Problem
Photonic component manufacturers face limited access to domestic Indium Phosphide (InP) foundries, high shipping costs, and fragmented optical packaging services, which constrain scaling of AI, data‑center, defense, and aerospace applications.
Solution
Combined Semiconductor (CSI) operates a U.S.-based, open‑access InP fab that produces 150 mm wafers and integrates front‑end device fabrication with on‑site optical packaging and testing. By consolidating these steps in a single facility, CSI reduces logistics complexity, lowers unit costs, and improves yield consistency for high‑volume photonic products. The company’s platform enables fabless customers to transition from prototype to commercial production without relying on overseas or captive fabs. CSI also offers scalable optical I/O and interconnect components tailored to AI and data‑center infrastructure, ensuring a secure domestic supply chain.
Target Audience
Primary customers are fabless photonic device designers, AI and data‑center hardware manufacturers, and defense/aerospace firms requiring high‑volume InP components and integrated optical packaging.
