Design and development of power efficient satellite optical links

空间技术、数据和服务已成为我们日常生活中不可或缺的一部分。由于卫星的全球覆盖，导航、全球通信和地球观测是这种依赖的最突出的例子。所有这些服务都严重依赖在轨卫星、地面用户和控制站之间的通信联系。非地球静止轨道卫星通信被广泛认为是卫星通信的下一个重大革命之一。该项目是在超密集低地球轨道（LEO）卫星星座的新兴领域提出的，该领域需要开发高容量卫星链路，以允许位于非常稀疏的地面用户之间的低延迟连接。这项工作将重点放在光通信技术上，这将带来前所未有的高传输速率、数据安全性和弹性。更具体地说，该项目涉及开发适用于空间环境的高数据速率光链路的光电设备。该学生将负责设计和开发一个用于卫星光通信链路的光子学子系统。

Space technologies, data and services have become indispensable in our everyday lives. Navigation, global communication and Earth observation are the most prominent examples of such reliance owing to satellites' global coverage. All these services are critically dependent on the communication links between the satellite in orbit, ground user and control stations. Satellite communication at non-geostationary orbits is widely considered one of the next major revolutions in satellite communication. This project is proposed in the emerging area of ultra-dense low Earth orbit (LEO) satellite constellations which demand developing high capacity satellite links to allow for low-latency connectivity between ground users which can be very sparsely located. The work will focus on optical communication technologies, which bring unprecedentedly high levels of transmission rates, data security and resilience. More specifically, the project concerns developing opto-electronics devices for high data-rate optical links which are suitable for the space environment. The student will be working on the design and development of a photonics sub-system to be used in satellite optical communication links.
