Nature Communications, Published online: 31 July 2026; doi:10.1038/s41467-026-76129-8 This study breaks the high-Q linewidth bottleneck of all-optical broadcasting using a parity-time symmetric coupled microcavity with engineered exceptional points. It achieves over 100 channel on-chip broadcasting spanning 200 nm with aggregated Terabit-per-second data rates and validates its feasibility for on-…

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.
