Abstract
Methods and apparatus for providing dispersion-managed dissipative Kerr solitons on-chip are provided. Microresonators are also provided for producing such solitons. The solitons may be enabled by real-time dynamical measurements on frequency combs. Methods are further provided to determine the temporal structure of the intracavity field in both the fast time axis, with ultrafast time-lens magnifiers at 600 fs timing resolutions, and the slow time axis via optical sampling with a synchronized fiber frequency comb reference. An order-of-magnitude enlarged stability zone of the dispersion-managed dissipative Kerr solitons is achieved versus the static regimes.
