Vacancy No. 1103/2019

Doctoral Researcher (f/m/d)
Project B3 “Frequency combs”

Job description

The Collaborative Research Center “Wave phenomena – analysis and numerics” (CRC 1173) is funded by the German Research Foundation (DFG) since 2015. Its goal is to analytically understand, numerically simulate, and eventually manipulate wave propagation under realistic scenarios by intertwining analysis and numerics.

The Project B3 “Frequency combs” (www.waves.kit.edu/B3) aims at establishing dedicated techniques that allow to understand and quantitatively describe frequency comb generation in Kerr-nonlinear optical microresonators. These techniques will be verified experimentally in a joint effort of researchers from electrical engineering and mathematics and shall build the base for theory-guided design of novel chip-scale frequency comb generators.

We seek an ambitious doctoral researcher with strong interest both in experimental and theoretical aspects of nonlinear optical systems. Your work will focus on experimental aspects of the project and comprise design, fabrication, characterization, as well as functional demonstration of chip-scale frequency comb sources. At the same time, you will closely work with peers with theoretical focus to advance and refine the underlying quantitative models and to use them for exploring novel device and comb generation concepts. You will have the opportunity to attend conferences, workshops and summer schools. Engagement in teaching is encouraged.

We provide an inspiring, attractive, interdisciplinary, and internationally recognized scientific environment with access to excellent facilities of the KIT, a wide scope of advanced training options within our integrated research training group, and flexible working time models. Our CRC aims at the implementation of equal opportunities, it promotes diversity and supports persons with childcare or eldercare responsibilities as well as persons with disabilities. Funds for travel and guests are available through the CRC.

Personal qualification

The following qualifications are required seeking your consideration for this position:

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