AI总结:

本研究针对声子在固体信息处理中未被充分利用的问题,开发了吉赫兹声子构建模块库,并构建了大规模可编程声子集成电路,实现了超紧凑声功率分配器等器件,确立了声子集成作为信息处理第三大支柱的地位。

摘要:

电子和光子芯片通过功能元件的大规模集成彻底改变了信息技术,但声子作为固体中的基本信息载体仍未得到充分重视。在此,我们展示了用于复杂信号处理的大规模可编程声子集成电路(PnICs)。我们开发了一套全面的吉赫兹频率声子构建模块库,用于控制声波传播、偏振和色散。结合这些元件,我们展示了一款超紧凑的1×128片上声功率分配器,其集成密度达到前所未有的3,000/cm²;一款具有3.8 MHz分辨率的21端口声学频率解复用器;以及一款四通道可重构频率合成器。这项工作确立了可扩展的声子集成作为继电子和光子之后信息处理的第三大支柱,使得能够结合这三个领域的混合芯片成为可能,以用于高级信号处理和量子信息应用。

英文摘要:

Electronic and photonic chips revolutionized information technology through massive integration of functional elements, yet phonons as fundamental information carriers in solids remain underestimated. Here, we demonstrate large-scale programmable phononic integrated circuits (PnICs) for complex signal processing. We developed a comprehensive library of gigahertz-frequency phononic building blocks that control acoustic wave propagation, polarization, and dispersion. Combining these elements, we demonstrate an ultra-compact 1$\times$128 on-chip acoustic power splitter with unprecedented integration density of 3,000/cm$^2$, a 21-port acoustic frequency demultiplexer with 3.8~MHz resolution, and a four-channel reconfigurable frequency synthesizer. This work establishes scalable phononic integration as the third pillar of information processing alongside electronics and photonics, enabling hybrid chips that combine all three domains for advanced signal processing and quantum information applications.
