DOI: 10.1109/tcsii.2022.3167673
Abstract: Coherent techniques, used for high-capacity optical links, conventionally use high-speed ADCs and digital signal processing, which make them power hungry. For short-reach coherent links such as data center interconnects, power consumption, form factor, cost, and… read more here.
