项目摘要

With this proposal I apply only for Sachmittel: 1) for a stay of Dr. Paul Gartner at the University of Bremen for a duration of two months, 2) for travel costs to present the results obtained in this project at the Photonics West conference in 2018, and 3) for publication of the obtained results.Together with the guest Dr. Paul Gartner, this project aims at developing new laser models for two-dimensional gain media. This includes novel laser structures, such as nanobeam cavities with semiconductor quantum-well gain media, and further extends to atomically thin transition-metal dichalcogenides that can act as gain material when placed on top of photonic crystal cavities. In contrast to conventional edge-emitting lasers, the structures that are to be investigated in this project are high-beta lasers, i.e. systems, in which high-quality nanocavities are used to tailor spontaneous emission itself, and in which lasing takes place in the presence of locally strong electromagnetic fields. Dr. Garters expertise with two-dimensional semiconductors and Greens' function methods will be of great value for the planned investigations.A second research topic concerns disorder effects in Jaynes-Cummings lattices, such as resulting from fluctuations in the spectral position of cavity modes, that are generally present in lithographically or epitaxially grown semiconductor structures. When several individual nanolasers are coupled to form a cavity array, the properties sensitively depend on such fluctuations. Based on preliminary work, in which ideal and identical building blocks of the array have been considered, together with Dr. Gartner disorder effects will be investigated. This will put us in a position to specify parameter conditions in connection with the fabrication of Jaynes-Cummings lattices made from qunatum-dot micropillar laser arrays. Furthermore, the developed models and the progress made will enable us to study quantum phase transitions and correlation effects under technically realistic conditions.

本建议仅适用于Sachmittel：1）Paul Gartner博士在不莱梅大学逗留两个月，2）在2018年Photonics West会议上展示该项目所获得的结果的差旅费，以及3）所获得的结果的出版物。与嘉宾Paul Gartner博士一起，该项目旨在为二维增益介质开发新的激光模型。这包括新颖的激光器结构，例如具有半导体量子阱增益介质的纳米束腔，并且进一步延伸到原子级薄的过渡金属二硫属化物，当放置在光子晶体腔的顶部时，其可以充当增益材料。与传统的边发射激光器相比，在这个项目中要研究的结构是高β激光器，即系统，其中高质量的纳米腔用于定制自发辐射本身，并且在局部强电磁场的存在下发生激光。Garters博士在二维半导体和格林函数方法方面的专业知识将对计划中的研究具有重要价值。第二个研究课题涉及Jaynes-Cummings晶格中的无序效应，例如由腔模光谱位置波动引起的，通常存在于光刻或外延生长的半导体结构中。当几个单独的纳米激光器耦合形成一个腔阵列时，其特性敏感地依赖于这种波动。基于初步的工作，其中理想的和相同的积木的阵列已被认为是，连同博士。这将使我们能够指定与由量子点微柱激光器阵列制成的Jaynes-Cummings晶格的制造有关的参数条件。此外，所开发的模型和取得的进展将使我们能够在技术上现实的条件下研究量子相变和相关效应。
