Demonstration of scalable, flat, and high-throughput data center architecture based on arrayed waveguide grating routers

We designed and experimentally demonstrated a scalable datacenter architecture with intra-cluster all-to-all topology and flat inter-cluster interconnection based on wavelength routing in AWGRs. Experiments show 97% intra-cluster throughput for uniform random traffic, and error-free inter-cluster communication at 10 Gb/s.
