Stabilization of a Kerr frequency comb oscillator

Opt Lett. 2013 Aug 1;38(15):2636-9. doi: 10.1364/OL.38.002636.


We study stability and spectral purity of a microresonator-based Kerr frequency comb oscillator experimentally and observe a correlation between the frequency of the continuous wave laser pumping the nonlinear resonator and the repetition frequency of the comb. This correlation is used in a proof-of-principle demonstration of a Kerr frequency comb stabilized with an optical transition of 87Rb.
