论文摘要
可以独立驱动/检测并易于与外部电路集成的耦合机电谐振器对于探索基于机械模式的信号处理至关重要。在这里，我们提出了一个室温声子腔机电系统，该系统由两个不同的谐振器组成：氮化硅机电鼓电容性地耦合到铝制的鼓。我们证明了在两色调驱动方案中机电诱导的透明度和扩增，并观察了影响两个可移动物体机械阻尼速率的声子腔。我们还基于线性耦合运动方程式开发了一个分析模型，该模型在经典限制中捕获了光学特征，并可以定量地拟合我们的测量值。我们的结果在研究基于语音子腔的信号处理的研究中开辟了新的可能性，并可能在未来的量子制度中。
Coupled electromechanical resonators that can be independently driven/detected and easily integrated with external circuits are essential for exploring mechanical modes based signal processing. Here, we present a room temperature phonon-cavity electromechanical system, consisting of two distinct resonators: a silicon nitride electromechanical drum capacitively coupled to an aluminum one. We demonstrate electromechanically induced transparency and amplification in a two-tone driving scheme and observe the phonon-cavity force affecting the mechanical damping rates of both movable objects. We also develop an analytical model based on linearly coupled motion equations, which captures the optomechanical features in the classical limit and enables to fit quantitatively our measurements. Our results open up new possibilities in the study of phonon-cavity based signal processing in the classical and potentially in the future in the quantum regimes.
