Integrated optics permeate datacenter networks.

The article discusses the use of photonic integrated circuit (PIC) and silicon photonics-based optical engines in data center network. Topics discussed include resolving issues related to packaging fiber-optics links with the switch application-specific integrated circuit, the introduction of software-defined networking (SDN) for the networking ecosystem, and growing application of silicon photonics in the integration of different optical devices into a single silicon die.
