Globecom 2019: Daniel Blumenthal Keynote

As Hyperscale data centers become prevalent, switch ASIC chips,  the engines of the Data Center Interconnect (DCI), will grow from 12.8 Tbps  today to 100 Tbps and beyond, straining engineerable fiber optic interconnect solutions and their cost and energy resources. In this talk a new approach that leverages the properties of quiet light, spectrally-pure highly-stable light developed for large scale physics experiments, to bring ultra-high capacity long-haul coherent optical solutions into the DCI without energy consuming electronics. The FRESCO project based on this approach (FREquency Stabilized Coherent Optical WDM Links for Low Energy DCIs), funded under the ARPA-e OPEN-2018 program, will be described and future opportunities and challenges discussed.
