ABSTRACT: Optical frequency combs (OFCs), with the precisely controlled spectral lines spanning over a broad spectrum, have made great impacts on frequency metrology, optical clockwork, precision navigation, high-capacity communication, and molecular fingerprinting over the past decades. Recent innovations in integrated photonics and nonlinear cavity dynamics further enable photonic frequency combs (PFCs) that hold the promise of bringing OFCs onto the chip and into applications requiring compact footprint, low power consumption, large comb spacing, and access to unconventional spectral region. In this talk, I will present our recent work on PFC generation in several different platforms to cover a wide range of parameter space. I will also present our recent work that shows the promise of these PFCs for biomedical applications.
