Agrawal, DK and Woodhouse, J and Seshia, AA (2013) Observation of locked phase dynamics and enhanced frequency stability in synchronized micromechanical oscillators. Physical Review Letters, 111. ISSN 0031-9007Full text not available from this repository.
Even though synchronization in autonomous systems has been observed for over three centuries, reports of systematic experimental studies on synchronized oscillators are limited. Here, we report on observations of internal synchronization in coupled silicon micromechanical oscillators associated with a reduction in the relative phase random walk that is modulated by the magnitude of the reactive coupling force between the oscillators. Additionally, for the first time, a significant improvement in the frequency stability of synchronized micromechanical oscillators is reported. The concept presented here is scalable and could be suitably engineered to establish the basis for a new class of highly precise miniaturized clocks and frequency references. © 2013 American Physical Society.
