Dissipative Kerr solitons formed in high-Q optical microresonators provide a route to
miniaturized optical frequency combs that can revolutionize precision measurements,
spectroscopy, sensing, and communication. In the past decade, a myriad of integrated
material platforms have been extensively studied and developed to create photonic-chip-
based soliton combs. However, the photo-thermal effect in integrated optical
microresonators has been a major issue preventing simple and reliable soliton generation …
