Postdoc in High-Performance Optical Transmission Systems at Danmarks Tekniske Universitet

High-capacity optical transmission of data has been a prerequisite for the Internet reaching its current omnipresence in people’s lives. As innovation in all aspects of society includes an ever-increasing level of connectivity, optical data transmission must continue to evolve rapidly. After an era where wavelength multiplexing has been a main driver in increasing data transmission, many researchers and system providers now believe that spatial multiplexing may be the next viable technology to continue this necessary increase of data transmission.

This postdoc project, will investigate spatial multiplexing in the form of multi-core optical fibre used for long-haul data transmission. The project will target demonstration of record-breaking reach and data throughput in such a transmission system.

The Postdoc project will be nested in the High-Speed Optical Communications group (HSOC) at the Technical University of Denmark (DTU Fotonik). The HSOC group is engaged with research in optical communication technology at the highest international level. It is the expectation that this Postdoc project will become an integral part of many of the communication systems activities in the group.

The project will have access to on-site state-of-the-art experimental facilities for which the Postdoc is expected to become one of the main super-users.

Responsibilities and tasks

  • Design of an ultra-long-haul multicore fibre transmission system.
  • Implementation of the system including component selection and validation.
  • Detailed performance investigation of the transmission system.
  • System level investigation of other advanced functionalities in optical communication systems. This could include optical signal processing, advanced modulation or coding schemes, compensation of optical nonlinearities or signal regeneration.

The exact research activities will be continuously adapted to align with the international state of the art and the Postdoc candidate’s ideas and interests.


Candidates should have a PhD degree or equivalent.

The successful candidate is expected to have experience and expertise in one or more of the following subjects

  • Optical communication systems.
  • Optical fibre technology.
  • Digital signal processing for communications.
  • Scientific method in research.
  • Good communication skills in English, both written and spoken.
