Suppression of optomechanical parametric oscillation in a toroid microcavity assisted by a Kerr comb

We demonstrate the suppression of cavity optomechanical parametric oscillations with the generation of a Turing pattern comb (Kerr comb) in an anomalous dispersion toroidal microcavity. If the pump light alone influences the optomechanical oscillation, it should be amplified because the strong pump light is blue-detuned from the cavity resonance. However, once the Kerr comb was generated, all the comb lines contributed to the cavity optomechanical behavior and the optomechanical oscillation was suppressed. A calculation taking account of the effective damping rate from all the comb lines is in good agreement with the experimental observation.
