Digital Coherent Transmission for Free-Space Optical Links

Starting date


Duration of contract

6 months


according to German TVöD 5

Type of employment


Your mission:

The optical communication group of DLR’s Institute of Communications and Navigation develop experimental laser communication systems for optical data links between airborne carriers such as airplanes or satellites and optical ground stations. The system development covers several disciplines such as optics, mechanics, electronics and programming. The successful applicant will support our team in the development of optical and optomechanical systems. Furthermore he/she will perform system tests and possibly will support the team during scientific measurement campaigns. It is an excellent opportunity to work in a cutting edge topic, gain experience on real optical hardware, and improve your engineering skills.

The subject offers several internship and Master Thesis topics like:

  • signal and channel analysis of the system and further development of post processing units with respect to the free-space scenario requirements
  • design, implementation, verification and performance analysis of coherent transmission schemes
  • measurements in realistic scenarios are expected
  • evaluation of measurements and analysis of the results in relation with the expected performance

Your qualifications:

  • study direction of optical, electrical engineering or communications
  • experience with digital signal processing
  • programming in Matlab / Simulink
  • experience with electrical / optical measurement technology
  • interest in free-space optics
  • programming in VHDL

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 unparalled scope to develop your creative ideas and accomplish your professional objectives. Reconciling family and working life as well as equal opportunities for women and men are an integral part of our HR policy. We therefore strongly encourage applications from women. Disabled applicants with equivalent qualifications will be given preferential treatment.
