Föger, D. (2013). Optical Characterisation of Quantum Dots embedded in Micropillars [Diploma Thesis, Technische Universität Wien]. reposiTUm. https://resolver.obvsg.at/urn:nbn:at:at-ubtuw:1-59439
In this thesis I focus on various methods for a theoretical and experimental characterisation of InAs quantum dots embedded in micropillars. My thesis is structured as follows:<br />In the rst chapter an introduction and a motivation for the fundamental research with quantum dots in micropillars is provided. Chapter 2 contains a basic description of self-assembled InAs quantum dots, their fabrication process as well as an overview of their physical properties. In the third chapter micropillars are described. At the end of this chapter a powerful method for the simulation of eigenmodes of micropillars is presented. Chapter 4 provides a short overview of the photon statistics of dierent light sources and introduces the second-order correlation function.<br />Chapter 5 summarizes the experimental work of my thesis. It can be organized into three parts, in which the rst provides an overview of our experimental setup.<br />The second part describes the basic measurements for an optical characterisation of quantum dots in micropillars and the third presents the most important experimental results.<br />A conclusion and an outlook at the end of my thesis provide a short summary of the major achievements and describe projects of our research group in the near future.
