Abstract
Significant progress has been made in the last years towards a better understanding and theoretical modeling of Kerr-effect induced generation of optical frequency combs in microresonators. However, the simultaneous interaction of hundreds or thousands of comb frequencies with the same number of modes of an optical resonator leads to complicated nonlinear dynamics that are far from fully understood. An important pre-requisite for modeling the comb formation process is the knowledge of phase and amplitude of the comb modes as well as the detuning from their respective microresonator modes. Here, we present comprehensive measurements that fully characterize optical microcomb states. We introduce a way of measuring resonator dispersion and detuning of the comb modes in a hot resonator while generating an optical frequency comb. The presented phase measurements show comb states with distinct π and π/2 steps in the relative comb phases that are not observed in conventional optical frequency combs.Citation
