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.

如何在纳米级的局限，夫妇和增强光是纳米素体的一个核心问题。已经发现，通过利用特定的纳米架构或几何形状，我们可以夫妇并增强光原子或分子。这将创建新的混合状态，这些状态本质上是一部分和部分的。在这个项目中，我们将使用与光相互作用的金属纳米结构探索一个新的概念，该金属纳米结构可以在同一1 nm腔中捕获分子和光。这使信号能够通过超过十亿倍的倍数放大，从而破坏了经典的衍射极限。该CDT项目的目的是构建一种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并评估设备性能。这将导致低能光学开关的潜力。
