Photonic-crystal waveguides have led to a new generation of integrated high-Q Kerr-nonlinear microresonators, in which linear and nonlinear dynamics can be strongly influenced and tailored. We discuss ultrashort pulse and frequency comb formation in such resonators, novel self- and sideband injection locking dynamics, as well as, methods for full phase-stabilization as needed for chip-based optical precision metrology.
