Mutual 3:1 subharmonic synchronization in a micromachined silicon disk resonator

Abstract: We demonstrate synchronization between two intrinsically coupled oscillators that are created from two distinct vibration modes of a single micromachined disk resonator. The modes have a 3:1 subharmonic frequency relationship and cubic, non-dissipative electromechanical coupling between the modes enables their two frequencies to synchronize. Our experimental implementation allows the frequency of the lower frequency oscillator to be independently controlled from that of the higher frequency oscillator, enablin… Show more

“…A huge amount of literature has been dedicated to internal resonances in the nonlinear dynamics community over the past 50 years, since they are commonly observed in macrostructures, for instance, in the case of nonlinear musical instruments. 8,9 For micro/nano resonators, internal resonance received increasing attention [10][11][12] over the past few years. In the special case of a resonator with two vibration modes of almost identical eigenfrequencies, a so-called one to one (1:1) internal resonance can be observed.…”

“…Internal resonance mediated through cubic nonlinearity has been observed in a variety of electromechanical systems including quartz crystals [12] and MEMS oscillators [13][14][15]. This behavior can be of practical value, since the finger print of internal resonance, usually seen as a plateau feature in the nonlinear response of the lower frequency mode, was suggested as a means to fix the oscillator's frequency and improve its stability [14].…”
