Two-dimensional Photonic-switched High-speed Interconnects for AI-driven Data Centre Networks

We present two-dimensional photonic-switched high-speed interconnects with a silicon $4 \times 4 \times 8 \lambda$ space-and-wavelength selective photonic switch for data centre networks. The switch enables 100Gbps wavelength-space routing for InfiniBand and supports a 1Gbps real-time video transmission over Ethernet, demonstrating its potential for AI-driven, high-bandwidth, agile networks.
