Opto-acoustic metasurfaces

该项目旨在开发高效的纳米级光源和声源，并将它们合并在超薄表面上。光和声波在宏观尺度上的相互作用每天都在使用，例如在无损检测和非接触式成像中。然而，对纳米级光-声相互作用的研究是新的，尚未充分发挥其潜力。该项目旨在开发超紧凑的光和声音源，有效地调整它们，同时利用它们，并有效地将它们转换为另一个，所有这些对于现实世界的应用都至关重要。这项研究有望改善使用光和声音的技术，包括显微镜和光谱学。

This project aims to develop efficient nanoscale light and sound sources and merge them on an extra-thin surface. Interactions between light and sound waves at the macroscopic scale are used every day, such as in non-destructive testing and contact-less imaging. However, research into nanoscale light-sound interactions is new and has not realised its full potential. This project intends to develop ultra-compact sources of light and sound, tune them effectively, harness them simultaneously, and convert one to another efficiently, all crucial for real-world applications. This research is expected to improve technologies that use light and sound, including microscopy and spectroscopy.
