China Just Commoditised the LiDAR Chip Europe Thought It Owned A Chinese photonics firm has won VCSEL development contracts from two overseas-listed LiDAR companies — and Europe's sensor stack now has a cost problem it didn't budget for. The VCSEL market is racing toward USD 5.84 billion by 2030, and European incumbents are about to find out whether they built moats or just margins. ## What happened in China Ruishi Technology (瑞识科技), a Chinese VCSEL chip developer, won development projects from two overseas-listed LiDAR companies. The contracts cover 2D addressable VCSEL arrays — the specific chip architecture that makes solid-state LiDAR viable at scale. This is not a research milestone. These are commercial development engagements with companies that sell into global automotive and industrial markets. The timing is pointed. China's commerce ministry tightened export controls and made supply-chain security a headline priority heading into 2026. European firms were already…
