Dissipation Assisted Frequency Comb and Chaos Generation in the Optomechanics

Dispersion and dissipation are the key parameters of the optical components. Generally, dissipation is an unfavorable factor. In this article, we designed a dispersion-dissipation hybird coupling optomechanical cavity and achieved dissipation-assisted frequency comb and chaos generation. We studied the bistable state and the spectrum of optomechanical cavity. We found that chaos and frequency comb can be effectively adjusted by adjusting the dissipation coupling. We given out the formation mechanism of the two types of frequency combs of the optomechanical cavity. Our result provides an effective way to achieving low threshold, adjustable frequency comb and chaos in an optical microcavity.
