🤖 AI Summary
To address the bandwidth limitations and high power consumption of electronic switching in large-scale optical interconnects, this paper proposes a scalable optical circuit-switching architecture tailored for programmable integrated photonic chips (PIPs). The architecture supports a port-agnostic, fully connected topology and introduces, for the first time, a graph-matching–based optimization scheduling algorithm specifically designed for PIPs. It integrates silicon photonics, wavelength-agnostic optical path provisioning, and dynamic reconfiguration control. Experimental validation demonstrates full connectivity across 32 ports: end-to-end optical path setup latency is under 1 μs, topology reconfiguration occurs at nanosecond scale, and power consumption is reduced by 90% compared to equivalent-scale electronic switches. This work overcomes fundamental bottlenecks of conventional switching paradigms and establishes a new paradigm for high-throughput, ultra-low-latency, energy-efficient, and reconfigurable optical networks.
