Optical satellite payload design: coherent communication system concept

Starting date

November 2021-January 2022

Duration of contract

6 months


up to German TVöD 5

Type of employment


The Group of Advanced Optical Technologies of DLR’s Institute of Communications and Navigation develops experimental laser communication systems for optical data links between satellites and optical ground stations as well as demonstrator platforms for testbed system verifications. The system development covers several disciplines such as optics, physics, electronics, programming and mechanics.

The successful applicant will support our team in the development of optical, photonic and communications systems for very-high-throughput satellite communications applications. Foremost, they will perform theoretical analysis and simulation of various techniques to realise analogue and digital signal transmission. Electrical and optical signal distortion analysis would conclude the theoretical analytical part, which shall be followed by experimental work on the laboratory prototype, where the relevant system parametres can be verified. Finally, the successful laboratory tests would then qualify the setup to be tested by the student with the team in an outdoor testbed.

It is an excellent opportunity to work in a cutting-edge topic, gain experience on real optical hardware, and improve your engineering skills.

Main Tasks:

  • optical communications systems design
  • interface definition between the sub-systems
  • performance analysis (link budget, SNR, BER)
  • setup of a laboratory demonstrator and its performance verification
  • programming of simulation tools (Python or Matlab) when necessary

Your qualifications:

  • study direction of electrical engineering, communications, technical physics or optics
  • experience with optical and/or RF communications technologies
  • experience in optical system design and testing is an advantage
  • interest in (satellite) optical communications

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalleled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (f/m/x). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
