DOI: 10.1038/s41467-021-21658-7
Abstract: Compact, low-noise microwave sources are required throughout a wide range of application areas including frequency metrology, wireless-communications and airborne radar systems. And the photonic generation of microwaves using soliton microcombs offers a path towards integrated,… read more here.
