POSTS ARE IMMEDIATELY AVAILABLE in the field of free-space optical communications
Scientist in the field of free-space optical communications and/or adaptive optics

Fraunhofer Society is the largest organization for applied research in Europe. One of over 60 Fraunhofer institutes, the Fraunhofer Institute of Optronics, System Technologies and Image Exploitation (IOSB) in Ettlingen supports research in areas such as real-time image processing, pattern recognition, and performance optimization of electro-optical systems.
The Adaptive Optics (AO) Group at Fraunhofer IOSB invites postdoctoral applications for immediate participation in the newly commencing project „Turbulence compensation for atmospheric and underwater environments“. The project is concerned with the development of new modalities of reliable transfer of signals through challenging random media, e.g. through water. In particular, the incumbent will participate in the conception of AO strategies counteracting the occurrence of branch points and scintillation and in their implementation in laboratory environment and under field conditions. The emphasis in the project is on laser-based communications and modelling of strong (or “deep”) turbulence.
Research activities in the Adaptive Optics Group at Fraunhofer IOSB revolve around imaging through turbulence (especially along horizontal paths and strong turbulence) and free-space laser communications. We develop simulations, theoretical models, image processing software and adaptive optics systems. Imaging and laser propagation through strong turbulence has unique challenges, quite different from astronomical adaptive optics, and therefore we rely on unconventional approaches to the problem. The Group has participated in several international collaborations and experiments and has had projects funded by foreign agencies, in particular from the aerospace and defense sector. More information about the AO Group at Fraunhofer IOSB can be found under optics

What we expect from you

The successful candidate will have experience with some or all of the following:

  • adaptive optics,
  • lasers,
  • interferometry,
  • opto-mechanical design & analysis,
  • systems implementation, optimization and alignment.

Candidates with moderate experience in optics but with strong background in telecommunications are also encouraged to apply, as are candidates with strong skills in simulations and theoretical modelling rather than in experimental, laboratory work.
Tasks of the incumbent will include:

  • experimental or simulation-based verification of novel adaptive optics modalities, including: the holographic wavefront sensor, wavefront sensorless AO, and/or interferometric approaches,
  • setting up the new laser communications laboratory,
  • establishment of the free-space communications link between Ettlingen and Karlsruhe,
  • taking part in field trials, operation of the existing Shack-Hartmann-based AO system,
  • Given the incumbent’s prior experience in telecommunications, more emphasis could be placed on implementation of the advanced multiplexing approaches, in particular orbital angular momentum multiplexing.

When compatible with the candidate’s background, theoretical modeling of problems in imaging and laser propagation could also be undertaken in addition to laboratory work. He/she is also expected to publish papers and give presentations at international conferences.

What you can expect from us

  • opportunity to work on challenging projects at the forefront of science
  • the chance to collaborate with the best scientists from around the world
  • work-life balance
Expected start date: as soon as possible.

Appointment, remuneration and social security benefits based on the public-sector collective wage agreement (TVöD). Additionally Fraunhofer may grant performance-based variable remuneration components.
In case of identical qualifications, preference will be given to severely disabled candidates.
The Fraunhofer-Gesellschaft is committed to providing equal career opportunities for men and women.
