Integrated nonlinear photonics can potentially revolutionize instrumentation, time standards, spectroscopy, and navigation.
This talk will review the nonlinear optics in integrated photonic platforms, and discuss the recent progresses on an integrable soliton frequency comb and Brillouin laser [1-2]. 
In addition, applications to on-chip optoelectronic systems including optical frequency synthesizer and optical clock will be covered in this talk [3].
