Photonic Mixture-of-Experts for scalable multi-task on-chip optical neural networks

Nature Communications, Published online: 03 June 2026; doi:10.1038/s41467-026-73983-4 Optical computing could accelerate AI, but struggles to scale optical neural networks for diverse tasks. Here, the authors demonstrate a scalable photonic mixture-of-experts chip that expands network capacity in width using parallel optical experts for multi-task processing.
