Dissipative Kerr solitons offer low power consumption, flexible line spacing, and CMOS compatibility, making them ideal for diverse applications [1]. However, their adoption still faces substantial challenges: low soliton power, and thermo-optic instability [2]. Numerous studies have attempted to solve these challenges separately, which often involve complex pumping methods [3], [4] or intricate cavity designs [5], [6]. While the traditional single CW pumping single cavity scheme is simple, current experimental demonstrations have achieved only few mW output soliton power [2]. In this work, we combine advanced device design with a novel pumping pathway to achieve deterministic generation of high-power single solitons in SiN microresonators, advancing soliton-based technologies.
