ScholarBank@NUS Repository. | Abstract: | The physics of light-matter interaction governs all the optical phenomena happening around us. In this century we are witnessing the evolution of optics and photonics at a nanoscale level where light interacts with nanostructured materials to exhibit fascinating physical phenomena. Although the complexity of the governing theories rapidly increases from time to time, our never-ending passion for exploring the secrets of Nature brings out new physics every day. This thesis is about such a realization of half-light half-matter particles called polaritons, in a novel artificial material platform called Metal-Organic Framework (MOF). We believe that our work provides an insight into the governing light-matter interaction processes in MOF microcrystals both experimentally and theoretically. We found that a strong light-matter regime is achieved in MOF microcrystals because of the coupling between Frenkel excitons and photonic modes developed inside the MOF crystalline cavity. The observation of such exciton-polaritons in a MOF microcavity has never been reported before. Unlike conventional cavities where exciton-materials are sandwiched inside an external cavity, the MOF crystal itself acts as a photonic cavity and an exciton material. | URI: | https://scholarbank.nus.edu.sg/handle/10635/166488 |
