Fully-Loaded Operation of 0.29-pJ/bit Wall-plug Efficiency, 81.9-Tb/s Throughput 32 × 32 Silicon Photonics Switch

We demonstrate 16-ch. × 32-Gbaud QPSK/probabilistically-shaped-64QAM WDM transmission by three/nine cyclic propagations through a fully-loaded 32×32 silicon photonics switch. Its nine-stage Clos network will have a throughput of 125 Pb/s (131,072 ports × 0.952 Tb/s). © 2021 The Authors
