The objective of this project is the utilization of light-matter-coupling in ZnSe-based monolithic microcavities. In this context, we will focus on three aspects. The emission of quantum dots implemented into microcavities will be investigated in the weak-coupling regime in coupled pillar microcavities. The special optical field distribution of their resonator modes will be used to realize an optical switching between the emitters. There exists a variety of technological applications for blue emitting Vertical-cavity surface-emitting laser (VCSEL). Hence, we will work on the realization of optically and electrically driven photon sources based on microcavities with ZnSe quantum wells as optically active material in the cavity. In order to achieve low threshold lasers we want to exploit the strong light-matter interaction in microcavities with a few quantum wells implemented. For this we will focus on structures with a lateral polariton confinement and analyze the influence on their optical properties. This lateral confinement will be realized in photonic wires and by utilization of gold grids on the sample surface. The stated topics are question of actual interest and will yield information on polariton propagation and coherence. Furthermore, the interaction between surface plasmons and polaritons will be investigated. The lateral confinement of the polaritons is expected to have a positive influence on the polariton relaxation and hence on the threshold for stimulated emission. In addition, a new concept for the generation of polaritons will be realized. We will investigate the potential coupling between Bragg modes and the exciton emission in ZnSe quantum wells to form Bragg polaritons.

本计画的目标是利用光物质耦合于硒化锌基单片微腔。在这方面，我们将重点关注三个方面。在弱耦合条件下，研究了柱型耦合微腔中量子点的发射特性。利用其谐振腔模式的特殊光场分布，实现发射极之间的光开关。蓝光发射垂直腔面发射激光器（VCSEL）有多种技术应用。因此，我们将致力于实现基于ZnSe量子威尔斯作为光活性材料的微腔的光电驱动光子源。为了实现低阈值激光器，我们希望利用强的光-物质相互作用的微腔与几个量子威尔斯实施。为此，我们将集中在结构与横向极化激元限制和分析其光学性能的影响。这种横向限制将在光子线中实现，并通过利用样品表面上的金网格来实现。所陈述的主题是实际感兴趣的问题，并将产生关于极化子传播和相干性的信息。此外，表面等离子体激元和极化激元之间的相互作用将被研究。极化激元的横向限制预计会对极化激元弛豫产生积极影响，从而对受激发射的阈值产生积极影响。此外，一个新的概念产生的极化激元将被实现。我们将研究在ZnSe量子威尔斯中布拉格模与激子发射之间的潜在耦合，以形成布拉格极化激元。
