Abstract:

This program on microLED datalinks addresses the bandwidth‑energy bottleneck limiting AI‑driven supercomputers. By scaling microLED optical links, the project targets sub‑1 pJ/bit energy use and >10.5 Tbps/mm data density over distances up to 10 meters, enabling point‑to‑point interconnects for CPUs, GPUs and HBM stacks.

Combining device, circuit and 3‑D integration expertise hybrid bonding and high‑density TSVs the consortium will manufacture microLEDs on 200 mm wafers using standard foundry technology, with a clear path to 300 mm scalability.

Why it matters: MicroLEDs offer a mature, low‑power alternative to copper or laser‑based interconnects that can deliver orders‑of‑magnitude speed gains, while sharply reducing power draw. Attendees will see the microLED-for-datacom roadmap, learn how the technology can accelerate AI workloads, lower data-center expenses, and open new opportunities for chipmakers, optical‑component suppliers and hyperscalers.
