How to confine, couple, and enhance light at nanoscale is a central question of nanophotonics. It has been found that by utilizing specific nano architecture or geometry we can couple and enhance the light to atom or molecules. This will create new mixed states that are part-light and part-matter in nature. In this project, we will explore a new concept in optics using metallic nanostructures interacting with light, that can trap both molecules and light in the same 1 nm cavity. This enables signals to be amplified by more than a billion-fold, allowing to break the classical diffraction limit. The objective of this CDT project is to construct an optical nanocavity tuned to molecular vibrations and investigate its interactions with light. The research will involve developing optical microscopy tools, analysing data, and creating theoretical models to explain the results and assess device performance. This will lead to the potential for low energy optical switches.

如何在奈米尺度上限制、耦合及增强光是奈米光子学的核心问题。已经发现，通过利用特定的纳米结构或几何形状，我们可以将光耦合并增强到原子或分子。这将创造新的混合状态，即部分光和部分物质的性质。在这个项目中，我们将探索一种新的光学概念，使用金属纳米结构与光相互作用，可以将分子和光捕获在同一个1 nm的空腔中。这使得信号能够被放大十亿倍以上，从而突破经典衍射极限。这个CDT项目的目标是构建一个调谐到分子振动的光学纳米腔，并研究其与光的相互作用。该研究将涉及开发光学显微镜工具，分析数据，并创建理论模型来解释结果和评估设备性能。这将导致低能量光开关的潜力。
