Job description

The High-Capacity Optical Transmission Lab at the Electro-Optics Communication (ECO) group at Eindhoven University of Technology is recruiting for a PhD Doctoral Candidate (DC) researcher to develop characterization techniques and methods for space division multiplexing (SDM).

The PhD student will participate in an international team in an EU-funded Doctoral Network project on Optical fiber higher order mode technologies and their application within communication, sensing and bio imaging (HOMTech). The project consists of 10 Ph.D. students at 6 European universities and 3 industrial partners. The project has partners from five different EU countries. All 10 Ph.D. projects are within the overall theme of higher order modes in optical fibers for application in telecommunication, optical sensing, and imaging.

This Ph.D. project will take place at TU/e. Successful candidates will spend secondments periods of no less than 3 months at Nokia Bell Labs in New Jersey, USA and at University Degli Studi Del L'aquila, Italy where state of the art SDM field deployed testbed is being constructed. There will also be common meetings with the other 9 Ph.D. students in the doctoral network, including 5 training schools.

The electro-optical communications (ECO) group in the Faculty of Electrical Engineering at TU/e is a globally recognised, leading scientific and applied research group focused on exploiting light for communication systems. We apply our knowledge in collaboration with other scientists at TU/e and more recently within the newly formed Eindhoven Hendrik Casimir Institute (EHCI) to develop the required solution for many of the relevant challenges in communications. Supported by a six year 50-million-euro structural funding, the group expertise spans from the fundamentals and physics of photonics, optics, the design, and fabrication of photonic integrated circuits (PICs) systems to exploiting optical linear/non-linear signal processing to unlock fiber capacity and relevant higher layer protocols required to operate modern optical communication networks. Additionally, the group is embedded in a seven-year 20-million-euro project developing quantum photonic systems and integrated photonics for Quantum secure communication systems and networks.

Based in the purposely built FLUX building at the TU/e Campus, the ECO group has access to 300m2 of labs for conducting experimental research and is supported by a state-of-the-art 800m2 cleanroom. With 11 tenured scientists and as many as 70 PhDs, postdocs and senior researchers, the ECO group is a vibrant and exciting research group perfectly suited for talented and ambitious scientists. The group is active in spin outs and starts-ups (e.g., Micro-align, PhotonX Networks and LuXisens Technology) and carries out bilateral industrial research with major stakeholders in the communications industry.

Responsibilities and tasks

Optical fibres supporting propagation of light in so-called higher order modes (HOMs) have gained major research interest in the last years. However, there are still quite a few obstacles to overcome before HOM fibres can be used for major commercial applications. This research program aims to develop novel Digital Signal Processing (DSP) for advanced characterisation techniques for space division multiplexed ultra-high-capacity optical transmission systems and high-capacity data transmission systems. Space division multiplexing (SDM) can utilise several uniquely different architectures such as few mode fibres, multicore fibres and few modes multicore fibres which requires specialised characterisation tools beyond what are commercially available, and which need to be flexible to address the multiple different fibre optic architectures which support SDM. The project will among others consist of the following tasks:

  • Develop characterisation tools which exploit both optical phenomena (e.g., spectral interference) and develop DSP to enable accurate and flexible characterisation methods.
  • Develop advanced DSP which outperforms zero forcing and MMSE equalisers. This novel DSP will be deployed on ultra-high capacity SDM systems for state-of-the-art data transmission experiments.
  • Implement novel DSP in test bed scenarios at TU/e and L'Aquila.
  • Job requirements HOMTech PhD student


    Candidates must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree in photonics, electro, applied physics or similar.

    Further obligations : The doctoral candidate (DC) is expected to travel to network partners under two secondments for a typical total duration of 3-5 months. Additionally, the DC is expected to participate in outreach activities including, but not limited to, YouTube videos, social media updates, participation in public events and campaigns, as well as dissemination to popular press. Furthermore, due to the mobility rules of the Marie Skłodowska- Curie program, the applicant must not have resided or carried out their main activity (work, studies, etc.) in Netherlands for more than 12 months in the 36 months immediately before their recruitment date.

    Approval and Enrolment

    The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at TU/e. For information about our enrolment requirements and the general planning of the PhD study programme, please see TU/e doctoral regulations.

    Conditions of employment

    The salary and appointment terms are consistent with the current rules for PhD degree students. For more information about working at TU/e please see here: employment information at TU/e. The period of employment is 4 years.

    Information and application

    If you can see yourself in this position and would like to find out more information, please contact Dr Thomas Bradley (t.d.bradley@tue.nl) or Dr C Okonkwo (cokonkwoattue.nl).

    Application Procedure

    We invite you to submit a complete application by using the 'apply now'-button on this page. The application should include a:

  • A cover letter explaining your motivation and suitability for the position.
  • A detailed Curriculum Vitae.
  • A written scientific report in English (MSc thesis, traineeship report or scientific paper).
  • Copies of diplomas with course grades (transcripts).
  • Your complete online application must be submitted no later than 1 February 2023.

    The recruitment is taking place following the https: // euraxess.ec.europa.eu/jobs/charter/code, which all candidates are encouraged to study.

    We look forward to your application and will screen it as soon as we have received it.

    Selection process : HOMTech is open to researchers regardless of gender, religion, ethnicity, disability, sexual orientation, political views, language, age, and nationality. Applications from highly qualified applicants from outside the EU will thus be equally considered to other applicants. The integration of refugees is an EU priority, and we will ensure equal opportunities to the researchers whose scientific careers have been interrupted. To ensure a gender balance in the project and work towards the Commission's own policies on narrowing the gap between the genders in research, should two applicants be found to be equally qualified the preference will be given to the one that will balance the gender distribution in the entire Network. After the deadline, all submitted applications will be checked against the defined admissibility and eligibility criteria (e.g., submitted electronically, readable, complete, in English, including grades and references), and applicants will be informed by email within two work weeks on the outcome. The following interviews and selection process will be carried out by a temporary Selection Committee constituted by the coordinator (when possible) and the supervisors. Evaluation criteria include Scientific background, capacity for creativity and independent thinking and leadership, mentoring and presentation abilities.

    Protection of personal data : The personal data of the applicants will be handled in compliance with applicable EU and national law on data protection (GDPR).
