| contents | We demonstrate precision enhancements in a timekeeping device at constant power and regardless of the operation frequency. Our timekeeping device is a laser-driven coupled-cavity system sustaining limit cycles. We quantify the precision of this device via the standard deviation of the limit cycle period, and demonstrate how it changes when varying the cavity length at constant laser power. Through a phase space analysis of the limit cycle fluctuations, we reveal how the proximity of different bifurcations determines the timekeeping precision of our device regardless of the input power and oscillation frequency. We expect that, as the miniaturization of computer clocks demands greater energy efficiency in the presence of strong fluctuations, our results can pave the way towards maximizing the precision of such clocks. |
