Venstra, W.J. (author), Van Leeuwen, R. (author), Van der Zant, H.S.J. (author)We demonstrate a strong coupling between the flexural vibration modes of a clamped-clamped micromechanical resonator vibrating at low amplitudes. This coupling enables the direct measurement of the frequency response via amplitude- and phase modulation schemes using the fundamental mode as a mechanical detector. In the linear regime, a frequency...journal article 2012
