摘要:

我们提出了一个单一的高应力,双夹氮化硅纳米机械梁的不同弯曲振动模式之间的非线性耦合的研究结果。在100 mK下进行测量,并使用磁动技术驱动光束。我们分别观察了模式的非线性行为,并通过在多个频率下驱动光束来测量它们之间的耦合。我们证明了不同的模式的谐振器相互耦合的位移诱导的张力在梁,这也导致了众所周知的Duffing非线性双固支梁。

英文摘要:

We present results from a study of the nonlinear intermodal coupling between different flexural vibrational modes of a single high-stress, doubly-clamped silicon nitride nanomechanical beam. The measurements were carried out at 100 mK and the beam was actuated using the magnetomotive technique. We observed the nonlinear behavior of the modes individually and also measured the coupling between them by driving the beam at multiple frequencies. We demonstrate that the different modes of the resonator are coupled to each other by the displacement induced tension in the beam, which also leads to the well known Duffing nonlinearity in doubly-clamped beams.
