At the Department of Electrical Engineering and Information Technology, Technische Universität Darmstadt, Germany, Institute for Microwave Engineering and Photonics two

Marie Skłodowska-Curie ITN "NETLAS" Early Stage Researcher/PhD positions

are available for 36 months, starting from 1st February and 1st of April 2020, respectively.

The positions are supported by the EU funded Marie Skłodowska-Curie Innovative Training Network, NETLAS (Grant No. 860807) (NExt generation of Tunable LASers for optical coherence tomography), a joint project of 15 universities, companies and hospitals in Europe. Students will spend most of their time in Darmstadt, Germany with secondments to at least one University and one industrial partner each. Research will focus on innovative solutions for swept sources for optical coherence tomography based on widely tunable 1550 nm VCSELs.

The first topic will target development and controlling of electrostatically tunable MEMS-DBR VCSELs to increase tuning speed. Hereby processing, modeling and characterizations are the main objectives. The second topic will investigate a novel means for tuning the effective cavity length of a VCSEL by including a material with a high electro-optical coefficient. Modelling, processing, characterization are the main objectives. Supervision will be provided in a European setting where specialized and complementary training will be provided at several sites as well as during network events.

At the time of recruitment, applicants must fulfill the following requirements:

  • (First) master degree not more than four years (full-time equivalent) ago
  • Not have resided or carried out their main activity (work, studies, etc.) in Germany for more than 12 months in the 3 years immediately prior to appointment
  • Degree in Physics, Material Sciences or Electrical Engineering

For more Information see:

Ideally, the applicants have a solid background in the following topics:

  • Theoretical and experimental optics
  • Experience with processing in a clean room environment
  • Knowledge of Matlab and Comsol are a plus

We expect excellent, independent research and are supporting publications at renowned international conferences and in leading scientific journals.

The applicant will be paid a full-time salary, subject to Marie Skłodowska-Curie regulations. Moreover the applicant will get in touch with numerous labs and research facilities around Europe as well as visit and present their work at international conferences.

Opportunity for further qualification (doctoral dissertation) is given. The fulfillment of the duties likewise enables the scientific qualifications of the candidate.

The Technische Universität Darmstadt intends to increase the number of female employees and encourages female candidates to apply. In case of equal qualifications applicants with a degree of disability of at least 50 or equal will be given preference.

Your application should include your curriculum vitae, MSc/Diploma certificates and grades, and a letter of motivation stating your interest in the position and topic. An optional reference letter from the Master thesis supervisor will be helpful. Please send your electronic application to Prof. Sascha Preu ( with the subject “Application ITN-NETLAS”.
