Inside CEA-Leti’s Push to Industrialize MicroLED Interconnects
Jan. 15, 2026 –
Recognizing that microLED data links depend on tightly coupled technology bricks, CEA-Leti is launching a multilateral partnership to co-develop scalable optical interconnects for future AI systems.
As AI systems scale toward ever-denser GPU clusters and memory-heavy architectures, interconnects are emerging as a primary bottleneck. Compute performance continues to grow exponentially, but the links between processors, accelerators, and memory are struggling to keep pace—both in power efficiency and reliability.
Against that backdrop, CEA-Leti is launching a new three-year multilateral R&D program aimed at accelerating microLED-based optical data links for short- to mid-range, ultra-high-bandwidth communications.
