Vacancy No. 1139/2019

PhD candidate (f/m/d)

Job description

We are currently looking for an ambitious PhD candidate with strong theoretical and/or experimental background to join our research group as part of the Innovative Training Network of the European Commission MICROCOMB "Applications and Fundamentals of Microresonator Frequency Combs". This pan-European initiative addresses theoretical and experimental aspects of interdisciplinary importance related to microresonator frequency comb sources and to the corresponding applications in the fields of high-precision metrology, high-speed data transmission, and ultrafast signal processing.

The PhD project aims at concepts for hybrid multi-chip integration of frequency comb generator modules, combining microresonators, pump lasers, and monitor diodes in a single chip-scale package. To this end, we will use advanced 3D-nanoprinting techniques for in-situ fabrication of single-mode waveguides that connect optical chips. The project covers the design and simulation of the structures, the fabrication and characterization, as well as proof-of-concept demonstrations. We expect to show the viability of integrated comb source modules for applications in communications, signal processing, and metrology.

For this project, we can build upon a scientifically sound base of ongoing research activities. We offer an inspiring, attractive, interdisciplinary, and internationally recognized scientific environment with access to excellent research facilities.

Personal qualification

You must have an outstanding Master in Electrical Engineering or Optics and Photonics. A solid background in optics, particularly guided-wave optics or photonic integration is required and the applicants should be experienced in electromagnetic simulations (CST Studio Suite, COMSOL Multiphysics, Lumerical FDTD Solutions etc.). We expect excellent writing and oral communication skills along with the ability to work independently within an international team.

The successful candidate will receive a 36 month, full-time employment contract as per Marie Skłodowska-Curie Actions (MSCA) regulations for early stage researchers, and additional mobility and family allowances might be available for eligible researchers.

There are strict requirements within the Marie Skłodowska-Curie Innovative Training Networks. At the time of appointment, applicants must not have resided or carried out their main activity (work, studies, etc.) in Germany for more than 12 months in the 3 years immediately before the recruitment date. Applicants shall also be in the first four years of their research careers at the time of appointment and have not been awarded a doctoral degree.


Salary category 13, depending on the fulfillment of professional and personal requirements.
