题目:Principles and Applications of Surface Plasmon Nanophotonics
纳米表面等离子激元的原理与应用
摘要:
Storing a significant fraction of energy in electron gas, surface plasmon offers a highly effective mechanism for strong localization and enhancement of light. Naturally there has been extensive research worldwide for their applications in various aspects of photonics and optics. In this talk, three examples of latest research interest will be discussed. First, complex plasmonic nanostructures can exhibit strong near-field interaction among plasmon modes, leading to strongly hybridized modes analogous to the formation of molecular orbitals by the hybridization of atomic orbitals. This process can result in novel phenomena such as the Fano resonance. The study of mode hybridization not only sets up for a deeper understanding of optical interactions in nanostructures but also shows promise for applications in, for example, sensing. Second, plasmonic nanostructures can make a significant impact on solar energy conversion devices. In particular, plasmon enhancement can make the spectrum engineering by frequency upconversion a feasible approach for significantly improving photovoltaic device efficiencies. Finally, plasmonic nanomaterials can enable a new therapeutic approach with high specificity. We will show the latest results on the application of plasmonics on the treatment of bladder cancer.
