Coupled resonators represent a generic model for many physical systems. In this context, a microcantilever is a multimode resonator clamped at one end, and it finds extensive application in high-precision metrology and is expected to be of great potential use in emerging quantum technologies. Here, we explore the microcantilever as a flexible platform for realizing multimode nonlinear interactions. Multimode nonlinear coupling is achieved by (1:2) internal resonance (IR) and parametric excitation with efficient coherent energy transfer. Specifically, we demonstrate abundant tunable parametric behaviors via frequency and voltage sweeps; these behaviors include mode veering, degenerate four-wave mixing (D4WM) with satellite resonances, partial amplitude suppression, acoustic frequency comb (AFC) generation, mechanically induced transparency (MIT), and normal-mode splitting. The experiments depict a new scheme for manipulating multimode microresonators with IR and parametric excitation.

微悬臂梁谐振腔内共振引起的多模非线性耦合

耦合谐振器代表了许多物理系统的通用模型。在这种情况下，微悬臂梁是一种固定在一端的多模谐振器，在高精度计量学中得到了广泛的应用，并有望在新兴的量子技术中具有巨大的潜力。在这里，我们探索微悬臂梁作为实现多模非线性相互作用的灵活平台。多模非线性耦合是通过（1：2）内部谐振（IR）和具有有效相干能量传递的参数激励来实现的。具体来说，我们通过频率和电压扫描展示了丰富的可调参数行为。这些行为包括模式转向，具有卫星共振的简并四波混频（D4WM），部分幅度抑制，声频梳（AFC）生成，机械感应透明度（MIT），和普通模式拆分。实验描述了一种利用IR和参量激励操纵多模微谐振器的新方案。
