In the last 15 years there has been remarkable progress in boosting optical storage time in micro and millimeter-scale optical resonators. Chip-based devices attain Q factors of nearly 1 billion and micro-machined crystalline devices provide Qs exceeding 100 billion.  Extremely large resonant build-up effects are possible in these devices.  And these have created new perspectives for access to all nonlinear phenomena at milliWatt and even microWatt power levels.  Whole new classes of chip-integrated devices have resulted from this capability.  After reviewing the nonlinear physics of high-Q resonators, current work at Caltech on chip-based soliton microcombs and high-coherence Brillouin lasers will be discussed.  The application of these different phenomena to microcombs for optical frequency synthesis and miniature ring laser gyroscopes will be described.
