Advertised Positions

Postdoctoral Researcher (f/m/d) in the Field of Nonlinear Optics and Photonic Integration


Academics / Scientists / Engineers (master´s degree) (f/m/d), PhD students (f/m/d)

Job description

The position is embedded into an international research project, funded by the German Research Association (Deutsche Forschungsgemeinschaft, DFG) and the French Agence Nationale de la Recherche (ANR). The project aims at exploring, designing, implementing, and experimentally demonstrating a novel class of chip-scale frequency comb sources that combine the distinct advantages of soliton Kerr combs relying on silicon nitride (Si3N4) waveguides and quantum-dash mode-locked lasers (QD-MLLD) based on III-V materials while overcoming the respective weaknesses. To this end, the activity brings together researchers from electrical engineering and physics to address the challenges from both a theoretical and an experimental direction.

Your work will comprise the development of concepts for hybrid comb sources, simulation and design of the photonic integrated circuits, the development of the coupling interfaces between III-V devices and Si3N4 devices based on so-called photonic wire bonds, as well as the characterization and functional demonstration of the fabricated devices. You will closely cooperate with peers from electrical engineering and physics to demonstrate the functionality of the comb sources with and to explore their viability in ultra-wideband communications, optical ranging, or photonic-electronic signal processing. You will have the opportunity to attend conferences, workshops and summer schools. Engagement in teaching is encouraged.

The opportunity for a doctorate is given.

Personal qualification

  • Excellent Master, PhD, or an equivalent degree in Electrical Engineering, Photonics or Physics.
  • Strong theoretical and/or experimental background in optics, particularly nonlinear optics, photonic integration, guided-wave optics, or laser optics.
  • We expect excellent writing and oral communication skills along with the ability to work independently within an international team.


The remuneration occurs on the basis of the wage agreement of the civil service in TV-L E13, depending on the fulfillment of professional and personal requirements.
