The goal of this research project is the fabrication of semiconductor nanostructures, which are optimized for quantum optical studies, and the optical characterization of them. These efforts form the basis for the studies of the other involved experimental groups. The main areas of the present work are: 1) Growth of quantum wells and quantum dots for studies of light squeezing. A further patterning of these samples into periodic arrays with the period given by the light wavelength should result in intense emitters of squeezed light. 2) Fabrication of microresonators with three dimensional light confinement . Depending on the task to be addressed (for example, weak or strong coupling of electronic and optical excitations) different types of quantum dots shall be implemented into the resonators. The microresonators will also be used to obtain lasers with large spontaneous emission coupling factors. The fabrication will be accompanied by a detailed optical characterization of the structures, for which we will use cw and time-resolved spectroscopy.

该研究项目的目标是制造半导体纳米结构，这是优化量子光学研究，以及它们的光学特性。这些努力为其他相关实验组的研究奠定了基础。本论文的主要工作包括：1）生长量子威尔斯阱和量子点，研究光场的压缩效应。将这些样品进一步图案化成具有由光波长给出的周期的周期阵列，应该会导致强烈的压缩光发射器。2)具有三维光限制的微谐振器的制作。根据要解决的任务（例如，电子和光学激发的弱耦合或强耦合），不同类型的量子点应被实现到谐振器中。微谐振器也将用于获得具有大的自发辐射耦合因子的激光器。制造将伴随着详细的光学表征的结构，我们将使用连续波和时间分辨光谱。
