| Popis: | In this paper, we presented the electrostatic tuning functions of the coupling factor for the weakly coupled resonators (WCRs) for the first time. A WCRs system with two mechanical coupled double-ended-tuning-fork (DETF) resonators is designed, fabricated and tested to verify the tuning theory. In consistency with the theoretical expectations, the experimental results show that the coupling factor is in a quadratic function with the bias voltage, and the coupling factor exponentially decays with the relevant geometry parameters. A large tunable range of the coupling factor with the minimum value of ∼0.000917 and the maximum value of ∼0.00196 is obtained by tuning the bias voltage applied on the WCRs. It lays the foundation for controlling the sensitivity and resolution of the WCRs based sensors. |
