Femtosecond quantum optics with semiconductor-metal hybrid nanostructures

提出的项目目标是在单个自组装半导体量子点中使用单个光子进行单电子的超快速初始化，操作和读出。光场与纳米物体之间的有效耦合由光学天线提供。利用超快泵浦-探针光谱技术研究了量子点-金属纳米天线混合系统的超快动力学。为了进一步增加光-物质耦合，将混合系统置于光学微腔中，或使用Tamm等离子体结构。

The goal of the proposed project is the ultrafast initialization, manipulation, and readout of single electrons with single photons in a single self-assembled semiconductor quantum dot. The efficient coupling between the light field and the nanoobject is provided by an optical antenna. The ultrafast dynamics in the quantum dot - metal nanoantenna hybrid system is studied via ultrafast pump-probe spectroscopy. For further increase of the light-matter coupling the hybrid system is placed into an optical microcavity, or a Tamm plasmonic structure is used.
