Optical Network on Chip（oNOC）

oNOC (Optical Network on Chip) is an optical link‑based on‑chip interconnect architecture that delivers high‑bandwidth, low‑latency, low‑energy data transmission between multiple chips or cores within a single package.

By building a fixed or reconfigurable communication network topology—such as optical broadcast or wavelength‑division multiplexing topologies—on a photonic chip, different electronic chips can connect to one or more nodes within it, enabling data exchange over the on‑chip optical network.
