Keywords:Optical switching technologies for high-performance computing and data centers

We propose Flex-LIONS, a silicon photonic switch architecture with 21× less switching elements and 2.9× lower on-chip loss when compared with other reconfigurable switching fabrics at a scale of 64 ports. Benchmarking simulations indicate 1.33× reduction in packet latency and > 1.5× improvement in energy efficiency when compared with Fat Tree topologies.
