Piezoelectric microresonators have revolutionized modern wireless communication. While billions of these devices are in widespread use across a range of frequencies, materials, and device geometries, every piezoelectric microresonator in current use shares one common characteristic: they all manipulate (quasi) plane waves. While the ideas around waveguiding and strong confinement of acoustic fields have been around since the early days of ultrasonics research, they have had relatively little impact on modern devices. Building on recent developments in related fields, in particular integrated photonics and quantum computing, we outline the prospects for piezoelectric phononic integrated circuits, which can manipulate gigahertz acoustic waves in micrometer-scale waveguide geometries in low-loss chipscale platforms. We also discuss the main roadblocks, with an emphasis on insertion loss, which need to be addressed for these devices to have the desired impact on future systems.

压电声子集成电路


压电微谐振器彻底改变了现代无线通信。虽然数十亿个这样的器件在各种频率、材料和器件几何形状中得到广泛应用，但目前使用的每个压电微谐振器都有一个共同的特性：它们都操纵（准）平面波。虽然自超声波研究的早期以来，围绕波导和声场强限制的想法就已经存在，但它们对现代设备的影响相对较小。基于相关领域的最新发展，特别是集成光子学和量子计算，我们概述了压电声子集成电路的前景，该电路可以在低损耗芯片级平台中操纵微米级波导几何形状中的千兆赫兹声波。我们还讨论了主要障碍，重点是插入损耗，这些障碍需要解决，以便这些器件对未来的系统产生预期的影响。
