“…Since its observation by Huygens in the 17 th century, the synchronization of widely distinct systems have been shown to share remarkably universal features [1,2], fostering its exploration across many disciplines [3][4][5]. With the recent convergence among optical, mechanical and electrical waves using scalable microfabrication technologies, synchronization has emerged as a powerful tool targeted not only at technological applications, such as phaselock loops (PLLs) in radio-based communications [6][7][8], but also at developing the fundamentals of chaotic systems [9], injection locking [10][11][12], electro and optomechanical devices [13][14][15][16][17][18][19][20], nonlinear dynamics [21][22][23][24][25], network coupling [26][27][28][29], and quantum synchronization [30][31][32][33][34][35].…”

Experimental exploration of synchronization in scalable oscillator micro systems has unfolded a deeper understanding of networks, collective phenomena, and signal processing. Cavity optomechanical devices have played an important role in this scenario, with the perspective of bridging optical and radio frequencies through nonlinear classical and quantum synchronization concepts. In its simplest form, synchronization occurs when an oscillator is entrained by a signal nearby the oscillator's tone, and becomes increasingly challenging as the frequency detuning increases. Here, we experimentally demonstrate entrainment of a silicon-nitride optomechanical oscillator driven several octaves away from its 32 MHz fundamental frequency. Exploring this effect, we perform a 4:1 frequency division from 128 MHz to 32 MHz. Further developments could harness these effects towards frequency synthesizers, phase-sensitive amplification and nonlinear sensing.
