<Silicon Photonic Switch for Data Centers>

 Cloud computing and big data applications have fueled the rapid growth of datacenters. As the data traffic continues to grow at a fast pace, the majority of the traffic (about 75%) remains within the datacenter. The legacy networks are unable to handle the growing demand of cloud computing. New networks with flatter leaf-spine architecture are increasingly used to facilitate the communication between servers and storages. However, as the per-server link speeds continue to increase, it has become challenging for the CMOS (Complementary Metal-Oxide Semiconductor) switch to provide high radix at high port-bandwidth. Several hybrid datacenter network architectures that use optical switching to augment the electronic packet switching have been proposed. We have reported a new type of silicon photonic switch with MEMS (micro-electromechanical-system) switching mechanism.
