Prof. Xiankai SUN

Award Citation

Professor Sun is an expert on chip-scale integrated photonic, electronic, and mechanical devices and systems. He has so far published 170 refereed journal and conference papers. In this project, Professor Sun’s team aims to develop phononic integrated circuits on a silicon substrate, which enables phononic-optoelectronic integration for the next-generation integrated chips. This project will design all the phononic components and fabricate the phononic integrated circuits without suspended structures. For fundamental research, the developed area of integrated phononics will not only combine the traditional fields of nano-optomechanics and nanoelectromechanics, but also bring them to the level of integrated circuits, which can be used to explore the quantum properties of phonons and the interaction between phonons and other degrees of freedom on an integrated platform. For practical applications, the developed phononic integrated circuits will bridge the gap between today’s integrated electronics and integrated photonics, provide cost-effective solutions for signal processing, and enable multifunctional sensing on a chip.
