Acoustic frequency combs leverage unique properties of the optical frequency comb technology in high-precision measurements and innovative sensing in optically inaccessible environments such as under water, under ground, or inside living organisms. Because acoustic combs with wide spectra would be required for many of these applications but techniques of their generation have not yet been developed, here we propose an approach to the creation of spectrally wide acoustic combs using oscillations of polydisperse gas bubble clusters in liquids. By means of numerical simulations, we demonstrate that clusters consisting of bubbles with precisely controlled sizes can produce wide acoustic spectra composed of equally spaced coherent peaks. We show that under typical experimental conditions, bubble clusters remain stable over time, which is required for a reliable recording of comb signals. We also demonstrate that the spectral composition of combs can be tuned by adjusting the number and size of bubbles in a cluster.

使用液体中多分散气泡簇的振荡产生的光谱宽声频梳

声频梳利用光学频率梳技术的独特特性,在水下、地下或生物体内等光学无法接近的环境中进行高精度测量和创新传感。由于这些应用中的许多应用都需要具有宽光谱的声梳,但它们的生成技术尚未开发,因此我们提出了一种使用液体中多分散气泡簇的振荡来创建光谱宽声梳的方法。通过数值模拟,我们证明了由尺寸精确控制的气泡组成的簇可以产生由等距相干峰组成的宽声谱。我们表明,在典型的实验条件下,气泡簇随时间保持稳定,这是可靠记录梳状信号所必需的。我们还证明了可以通过调整簇中气泡的数量和大小来调整梳子的光谱组成。
