The subject of this project is the study of nano-scaled metal-organic plasmonic hybrid-systems in interaction with broadband femtosecond laser pulses. The investigated hybrid systems are composed of surface plasmon supporting metal nanostructures and organic nanofibers characterized by strong nonlinear characteristics and optical waveguiding properties. In our study we plan to systematically address and control the spatio-temporal response of these hybrid devices with respect to light-coupling and light-transport. The main experimental technique that will be applied in our study is the time-resolved and interferometric two-photon photoemission electron microscopy technique which enables us to monitor the ultrafast phase- and group dynamics of localized nano-optical fields on length scales that are well below the diffraction limit. Oligophenylene-based organic nanofibers exhibit broadband and almost loss-free optical waveguiding properties down to wavelengths as short as 400 nm. We believe that these fibers can play a crucial role as light-channeling sub-units and highly localized, nonlinear active emitters in future ultrafast nanophotonic devices.

该项目的主题是研究纳米级金属有机等离子体混合系统与宽带飞秒激光脉冲的相互作用。研究的混合系统由表面等离子体支持金属纳米结构和有机纳米纤维组成，具有强非线性特性和光波导特性。在我们的研究中，我们计划系统地解决和控制这些混合设备在光耦合和光传输方面的时空响应。我们研究中将应用的主要实验技术是时间分辨和干涉双光子光发射电子显微镜技术，该技术使我们能够在远低于衍射极限。基于低聚苯撑的有机纳米纤维在波长短至 400 nm 时表现出宽带且几乎无损耗的光波导特性。我们相信，这些光纤可以在未来的超快纳米光子器件中作为光通道子单元和高度局域化的非线性有源发射器发挥至关重要的作用。
