The generation of dissipative Kerr solitons in optical microresonators has provided a route to compact frequency combs of high repetition rate, which have already been employed for optical frequency synthesizers, ultrafast ranging, coherent telecommunication, and dual-comb spectroscopy. Silicon nitride (Si3N4) microresonators are promising for photonic integrated soliton microcombs. Yet to date, soliton formation in Si3N4 microresonators at electronically detectable repetition rates, typically…
