SFB 787: Semiconductor Nanophotonics: Materials, Models, Devices

合作研究中心“半导体纳米光子学：材料，模型，设备”结合了三个互补的研究领域，旨在开发新型纳米光子器件。材料生长、半导体纳米结构的先进表征和电子特性建模之间的独特相互作用构成了A区的核心要素，该区域基于两个最相关的光电半导体材料家族（III族砷化物和III族氮化物）。第二个领域B侧重于理论和数值模拟，从纳米材料的基本光学，电子和振动特性的描述到纳米光子器件的模拟。新颖的光发射器和放大器的设计、处理和表征是第三领域C关注的中心，其关注于大量的现实世界应用。这些研究活动是由综合研究培训组“纳米光子学学院”（项目D），汇集博士补充。具有不同科学背景的学生。RTG增加了一个广泛的教育组成部分，具有强大的跨学科特征，支持学生的职业发展，特别关注创业。总的来说，CRC第三阶段的研究活动将在前两个CRC阶段种植的许多种子中结出果实，伴随着许多新的纳米光子器件的实现及其在量子通信系统，数据传输和I/O引擎中的应用，以及对基础物理学的全面理解。一个中心目标是实现电驱动的量子密钥系统，该系统基于工作在高q比特率的q比特和纠缠光子发射器，以及它们在真实的信息网络中的实现。这包括实现确定性的单量子点发射器，用于产生按需的、频率锁定的、不可区分的光子。我们将实现基于GaN量子点的电泵浦紫外单光子发射器的室温工作。此外，腔量子电动力学效应对超小型垂直腔面发射激光器（VCSEL）和金属腔纳米激光器在多兆系统中的应用性能的影响将被探讨。此外，我们正计划开发一种基于VCSEL与硅光子混合集成的硅光子I/O引擎，以实现高效的芯片到芯片通信。最后，我们将展示AlGaN基电流注入深紫外激光二极管在诊断，传感和3D打印中的应用。这些纳米光子器件和应用的实现对CRC 787的第三个资助期构成了巨大的挑战，并将引发2019年以后的后续研究工作。我们还预计，CRC研究的成果将推动行业合作伙伴的创新，并产生分拆公司。

The Collaborative Research Centre "Semiconductor Nanophotonics: Materials, Models, Devices" combines three complementary areas of research aiming towards the development of novel nanophotonic devices. The unique interplay between material growth, advanced characterization of semiconductor nanostructures, and modeling of electronic properties constitutes the core element of area A based on two most relevant families of semiconducting materials for optoelectronics (group III-arsenides and III-nitrides). The second area B focuses on theoretical and numerical modeling ranging from the description of fundamental optic, electronic, and vibronic properties of nanomaterials to the simulation of nanophotonic devices. Designing, processing and characterizing of novel light emitters and amplifiers is the center of interest for the third area C focusing on a multitude of real-world applications. These research activities are complemented by the Integrated Research Training Group "School of Nanophotonics" (project D), which brings together Ph.D. students with diverse scientific backgrounds. The RTG adds a broad educational component with a strong interdisciplinary character that supports the students' career development with a special focus on entrepreneurship. Overall, the research activities in the third phase of the CRC will yield fruition of many seeds planted throughout the first two CRC phases, accompanied by the realization of a number of new nanophotonic devices and their application in quantum communication systems, data transfer, and I/O engines, as well as a comprehensive understanding of the underlying physics. One central goal is to realize electrically driven quantum key systems that are based on q-bit and entangled photon emitters operating at high q-bit rates and their implementation in real information networks. This includes the realization of deterministic single quantum dot emitters for the generation of on-demand, frequency-locked, indistinguishable photons. We will realize room temperature operation of electrically pumped UV single photon emitters based on GaN QDs. Also the impact of cavity quantum electrodynamics effects on the performance of ultra-small vertical cavity surface emitting lasers (VCSELs) and metal-cavity nano-lasers for applications in multi-terabus systems will be explored. In addition, we are planning to develop a silicon photonic I/O engine based on hybrid integration of VCSELs with silicon photonics for highly efficient chip-to-chip communication. Finally, we will demonstrate AlGaN-based current-injection deep UV laser diodes for applications in diagnostics, sensing, and 3D-printing. The realization of these nanophotonic devices and applications poses a formidable challenge for the third funding period of the CRC 787 and will trigger follow-up research efforts well beyond 2019. We also expect that the output of the CRC research will fuel innovations at industry partners and generate spin-off companies.
