Photonics for datacom

This work reports an overview about the contributions that photonics can add for the evolution of Data Centers, and it is pointed out how the combination of new photonic devices and optical communications can be considered as a valid recipe for high performance Data Center and their integration in the telecommunication network. In particular optical communication systems can satisfy all the aspects regarding the increasingly intelligent, low-latency and high-bandwidth connections among data centers. Furthermore, inside the data center rack, multiple processing cores are being integrated into a single photon-based chip to achieve higher processing power and energy consumption reduction.
