Tech­ni­sche Uni­ver­sität Ber­lin - Faculty II - Institute of Solid State Physics

Research Assistant - 0.75 working time - salary grade E13 TV-L Berliner Hochschulen

under the reserve that funds are granted

Working field:

Project work as part of the BMBF joint project "MultiCoreSPS" to develop quantum light sources for fibre-based quantum communication networks. The aim is to produce single-photon sources and microlasers in parallel in an innovative growth and nanofabrication approach and to couple them together as an advanced multifunctional emitter module to a multicore glass fibre for the simultaneous transmission of quantum information and classical information. Focal points of the development work are: Design, epitaxial growth and nanostructuring of single-photon sources and microlasers with emission in the telecom O-band at 1.3 µm, as well as their optical and quantum optical characterization. The main areas of work of the advertised position are:

  • Epitaxial growth of positioned semiconductor quantum dots with emission at 1.3 µm
  • Fabrication of MultiCoreSPS emitter modules using state-of-the-art nanotechnology techniques
  • Optical characterization of the grown structure and the fabricated emitter modules

The work is carried out in close cooperation with the project groups at the Technical University of Berlin and external partner groups.


  • Successfully completed scientific university studies (diploma, master's degree or equivalent) in physics or similar courses of study
  • Extensive knowledge as well as practical experience in the development and optical study of semiconductor devices is required
  • Ideally, in-depth knowledge in epitaxial growth and in the fabrication and study of quantum light sources based on semiconductor quantum dots is available
  • Communication and team skills are expressly welcomed
  • Good command of German and/or English required; willingness to learn either English or German is expected
