Silicon-Photonics Microring Links for Datacenters—Challenges and Opportunities

The rapid growth of warehouse-scale datacenters demands high-throughput optical interconnects that can span short-to-medium reach distances (<; few kilometers). Microring-based silicon-photonics links with single-mode fibers are highly promising for these applications. This paper presents an analysis of microring-based links from the holistic perspective of optical devices, CMOS circuits, and syst...
