Optoelectronic Integrated Circuits for Growing Datacenters: Challenge, Strategy and Evolution

摘要

Hyper scale datacenters drive amazing Ethernet volumes when thousands of servers are connected on one site, whichcreates high-density interconnect links between servers, switches and routers. Optical technologies are considered aspossible solutions to meet the future datacenter requirements in terms of cost, power consumption, port density andperformance. In this paper, evolution of optoelectronic integrated circuits technologies for reducing power consumption,improving port density and decreasing the cost of datacenter optical network, such as miniaturization of optoelectronicchips, high density optical coupling, electro-optical co-packaging and integration of nano-scale optical switch, will beoutlined, as well as the progresses in research and industrial activities.
