Abstract
A InP-based mode-locked laser photonic integrated circuit with a repetition rate of 10 GHz is optically synchronized to a SiN microresonator-based dissipative Kerr soliton with a rep- etition rate of 305 GHz. The synchronization is achieved through regenerative harmonic injection locking assisted with electro- optic division which results in an optical frequency division factor of 18×. The repetition rate of the dissipative Kerr soliton is stabilized through electro-optic division and transferred to the mode-locked laser, where we measure a fractional frequency instability in the repetition rate of 10−10 at 1 second with a 1/τ trend. Furthermore, we also stabilize the repetition rate of the dissipative Kerr soliton using the mode-locked laser's repetition rate beat as a feedback point.Citation
