报告题目：Topological integrated circuits using light and sound
报告人： 马静文 博士
The field of photonic/phononic integrated circuits is gaining significant momentum. In these integrated circuits, optical and acoustic waves can be electrically generated, manipulated, and detected on a single chip. Various nano-devices have been demonstrated, but suppression of undesired backscattering of optical and acoustic waves at nanoscale has been considered as a grand challenge on integrated platforms, which limits further increase of scalability and functionality of large-scale networks based on light and sound.
Originating from condensed-matter physics, topological insulators are a unique material that is insulating in its bulk but allows high-speed propagation of electrons on its edges. Similar concepts of topological insulators can also be applied to electromagnetic waves and acoustic waves, which are a promising strategy to suppress undesired backscattering in nanophotonic and nanoelectromechanical integrated circuits. In this presentation, I will introduce our recent experimental advances in topological nanophotonic and nanoelectromechanical devices on integrated platforms.
