Abstract
This work for the first time generates mechanical soliton frequency combs in a nonlinear micromechanical vibro-impact system. Particularly, a harmonically-driven resonator periodically strikes a separate, flexible beam resonator. Each impact excites a transient ring-down on the beam, and the periodic series of these responses generates frequency combs. By using amplitude-modulated (AM) pumping, the impacts become temporally isolated, creating a train of solitary mechanical pulses. These repetitive, solitary responses are analogies of circulating pulses in optical microresonators, thus producing mechanical soliton frequency combs. The impact mechanism also enables frequency up-conversion from a 135.04-kHz input to comb generation at 1.461 MHz, yielding 113 comb lines spanning a broad 481.6-kHz spectrum. This approach mitigates the need for precise modal frequency engineering required by conventional internal resonance.
