Inside CIOE: takeaways from China's biggest optoelectronics show

The recent CIOE exhibition highlights deep-seated shifts within the semiconductor and optoelectronics supply chain. Technologically, emerging areas such as LiDAR, Mini LED, and optical communication modules are gaining traction, signaling upstream material and equipment vendors to accelerate investments—particularly in critical materials like silicon carbide and photoresist. From a compliance standpoint, tightening international export controls are forcing companies to reassess supply chain resilience, especially concerning components sourced from Taiwan, China and Hong Kong, China, where operational costs are rising. In competitive terms, leading firms are pursuing vertical integration and M&A to solidify market dominance, while mid-tier players face intensified price competition. Over the next 12 to 24 months, optoelectronic components are expected to enter a phase of rapid evolution, particularly in automotive LiDAR and data center applications, likely triggering consolidation and standard-setting dominance by leading players.
