Location

ESTEC, Noordwijk, Netherlands

Our team and mission

The Optoelectronics Section provides functional support to ESA projects and carries out technological research (R&D) in the field of optoelectronic device technologies and applications. In particular, the Optoelectronics Section deals with the specification, development and characterisation of photonic component subsystems and active optical instruments, such as detectors and lasers operating in the UV to FIR wavelength ranges, fibre-optic sensors, lidars, optical communication systems and quantum technologies.

The Section is staffed with around 25 engineers supporting all ESA projects and offers a unique opportunity to contribute on the challenges related to optoelectronic technologies needed for ESA missions, spacecraft, instruments and equipment.

You are encouraged to visit the ESA website: http://www.esa.int

Field(s) of activity/research for the traineeship

The section is developing laboratory test setups and simulation tools in the areas of imaging detectors, optical communication and quantum communication.

Depending on the your interests, technical competences and project constrains in 2026/27, you will support one or more of these developments by for example:

  • Development of simulation tools for free-space optical or quantum communication systems
  • Testbed development of advanced spaceborne optoelectronic applications (for optical or quantum communication, optical detectors and/or lasers)
  • Integration and commissioning of upgraded laser induced contamination characterization setup
