The optical microcavities provide an excellent platform for strong light-matter interactions, due to their ultrahigh quality factor and small mode volume. The microcavities have been used for high sensitive sensing, low threshold lasing as well as single photon quantum gates by interacting with single emitters. Here, we explore the nonlinear optical processes in microcavities. By carefully engineering the geometry of microcavities, we demonstrated the coherent frequency conversion, narrow linewidth photon pair source, high efficient second harmonic generation, third harmonic generation, as well as frequency comb. These integrated nonlinear photonic devices, which are robust, compact and scalable, hold the great potential for future applications.
