声子波导（PnWG）是具有合理设计的周期性结构的设备，以操纵机械振荡并设计和控制声波的传播，从而允许波传输和路由的频率和频带选择，有望在具有各种感兴趣的组成材料的芯片级平台上进行经典和量子转换。它们可以结合到机电和光机械信号转导方案中。在这里，我们提出了新兴的微/纳米PnWG的概述，并提供未来的前景。我们评估的PnWG的典型结构设计，频率缩放，和声子带结构。基于不同的PnWG设计，材料的选择，制造技术和表征方案进行了讨论。对于经典的换能方案，提出了全声子集成电路的观点。对于新兴的量子应用，利用PnWGs作为通用接口和转导通道的潜力已经过研究。我们设想具有非凡传播特性的PnWG，例如非互易性和主动可调谐性，可以用非常规设计策略（例如，逆向设计）和先进材料（例如，货车范德瓦尔斯层状晶体），在经典和量子信号转导方案的开放机会。
Phononic waveguides (PnWGs) are devices with rationally designed periodic structures to manipulate mechanical oscillations and to engineer and control the propagation of acoustic waves, thus allowing for frequency and band selection of wave transmission and routing, promising for both classical and quantum transduction on chip-scale platforms with various constituent materials of interest. They can be incorporated into both electromechanical and optomechanical signal transduction schemes. Here, we present an overview of emerging micro/nanoscale PnWGs and offer perspectives for future. We evaluate the typical structural designs, frequency scaling, and phononic band structures of the PnWGs. Material choices, fabrication techniques, and characterization schemes are discussed based on different PnWG designs. For classical transduction schemes, an all-phononic integrated circuit perspective is proposed. Toward emerging quantum applications, the potential of utilizing PnWGs as universal interfaces and transduction channels has been examined. We envision PnWGs with extraordinary propagation properties, such as nonreciprocity and active tunability, can be realized with unconventional design strategies (e.g., inverse design) and advanced materials (e.g., van der Waals layered crystals), opening opportunities in both classical and quantum signal transduction schemes.
