With high bandwidth, low interference, and low power consumption, optical network‐on‐chip (ONoC) has emerged as a highly efficient interconnection for the future generation of multicore system on chips. In this paper, we propose a new path‐setup method for ONoC to mitigate contentions, such as packets, by recycling the setup packet halfway to the destination. A new, strictly non‐blocking 6 × 6 optical router is designed to support the new method. The simulation results show the new path‐setup method increases the throughput by 52.03%, 41.94%, and 36.47% under uniform, hotspot‐I, and hotspot‐II traffic patterns, respectively. The end‐to‐end delay performance is also improved.
