Visible light communication is an emerging field that is likely to form a key strand of the next generations of communications protocols offering increased bandwidth compared to radio frequency (RF) comms, license-free operation, and, in some situations, increased security.The development of micro-LED's and visible laser diode sources has enabled high data rate demonstrations of both line-of-sight and non-line-of-sight architectures, in particular when coupled with the exquisite sensitivity and timing capabilities of modern single-photon detectors. This project seeks to exploit advances in sources and detectors together with optical design to develop improved optical communications systems for challenging environments.These environments could be hampered by smoke, dust, mist, or turbid water. They could be complex and cluttered or have high background illumination. Terrestrial and space-borne systems may be addressed, with their particular challenges in size, weight, power, and robustness.Use will be made of Fraunhofer prototyping expertise with a view to real world deployment and demonstrations.Working within the Fraunhofer Centre for Applied Photonics alongside researchers, engineers, and other students, the EngD student shall also be required to work in multidisciplinary teams within project consortia spanning academia and industry.Free-space optical communication is on the cusp of really coming of age, both from necessity (RF spectral congestions) and modern developments in hardware and protocols. However, challenges remain in terms of systems practical for deployment in various scenarios, and ingenuity is required to find the approaches that best balance various competing factors (data rates, ranges, pointing stability requirements to name a few) such that systems can be compact and affordable. The precise use cases targeted will depend upon industrial and commercial priorities at the time the student begins the research phase of the programme.

可见光通信是一个新兴的领域，很可能成为下一代通信协议的关键部分，与射频通信相比，它提供了更高的带宽，免许可证操作，在某些情况下还提高了安全性。微型LED和可见激光二极管光源的发展使视线和非视线结构的高数据率演示成为可能，特别是当与现代单光子探测器的精致灵敏度和定时能力相结合时。该项目寻求利用光源和探测器的进步以及光学设计来开发改进的光通信系统，以适应具有挑战性的环境。这些环境可能会受到烟雾、灰尘、薄雾或浑浊水的阻碍。它们可能是复杂和杂乱的，或者有很高的背景照明。地面和空间系统在尺寸、重量、功率和坚固性方面都面临着特殊的挑战。我们将利用夫琅和费原型技术进行实际的部署和演示。在弗劳恩霍夫应用光子学中心与研究人员、工程师和其他学生一起工作，EngD学生还将被要求在横跨学术界和工业界的项目联合体中的多学科团队中工作。自由空间光通信即将成熟，这既是因为需要(射频频谱拥堵)，也是因为硬件和协议的现代发展。然而，就系统在各种情况下的实际部署而言，仍然存在挑战，需要独创性来找到最好地平衡各种竞争因素(数据速率、范围、指向稳定性要求等)的方法，以便系统可以紧凑且负担得起。具体针对的用例将取决于学生开始项目研究阶段时的工业和商业优先事项。
