Abstract

Optomechanical frequency combs with lower repetition rates have wide application perspectives in optics and photonics. Here, the effect of engineered dissipative coupling on the generation of optomechanical frequency combs in a photonic molecule configuration is studied when the optomechanical cavity operates in the resolved sideband regime. It is found that the strong dissipative coupling can significantly influence the system dynamics and improve the comb generation to simultaneously exhibit broad bandwidth, flat comb lines, and robustness to chaos. Furthermore, a scheme for realizing effective and controllable dissipative coupling between two optical microresonators is provided in a triple-cavity array under certain parameter conditions. It is confirmed that the effective dissipative coupling formed in the triple-cavity array can be used to improve the comb generation in the strong dissipative coupling case. Given the usefulness and accessibility of optomechanical frequency combs, our work may provide an interesting inspiration for future theoretical and experimental studies on optomechanical frequency combs.
