Our team and mission
Your field of research will be in a particular application of adaptive optics, namely the controlled wavefront pre-distortion of an optical communication beam, with the aim to minimize atmospheric turbulence effects. Your topic is applied research in optical satellite communications and a technology that promises data rates exceeding the capabilities of traditional radio communication systems by multiple orders of magnitude. Successful feasibility demonstration will enable the transformation of optical space to ground satellite communication from experiment to industrialization and commercial application.
You are encouraged to visit the ESA website: www.esa.int
Field(s) of activity/research for the traineeship
Your field of research is in the area of Adaptive Optics with Laser Guider Stars, with the final application of laser communications through the atmosphere. Laser beams characteristics are degraded due to detrimental effects like scintillation, beam spreading, beam wandering, angle of arrival fluctuations and wavefront distortion, caused by the propagation through a turbulent media like the atmosphere. In practical terms, the laser beam is distorted such that the detection and recovery of the communications signal modulating the optical carrier is severely affected in terms of quality of service (bit error probability and availability).
In particular, your tasks will be to:
• Perform the agreed applied research, contributing to advancing adaptive optics technology for its application to satellite communications
• Extend the use of adaptive optics for laser communications towards 24/7 operations
• Engage with both the optical communications and the astronomical adaptive optics communities to transfer know-how between research fields
• Publish in high-impact peer-review journals
• Participate in international conferences in the field and contribute to Scientific Organizing Committees
• Disseminate the research progress and achievements to both the scientific community and the general public through communication activities like seminars and outreach
• Provide the theoretical background and framework for the developments
• Analyze the operability of Sodium laser guide stars for wavefront determination outside the isoplanatic angle centered on the downlink beam
• Investigate alternative launch geometries for Sodium laser guide stars
• Investigate the application of polychromatic laser guide stars
• Liaise with both consortia by inspecting their hardware developments (at their premises) and by supporting bidirectional space to ground optical communication experiments at ESA’s optical ground station (OGS).
