Postdoc or PhD on "Bonding of hybrid waveguide structures" (published August 2022)

The Institute of Applied Physics (IAP) at the Friedrich Schiller University Jena has a long-standing tradition and competence in design, fabrication and application of active and passive optical and photonic elements. It is also very well-known for its developments in the area of high power laser technology and nowadys also in quantum optics. Collaborative projects with companies ensure practical relevance and feasibility.

For the fabrication of waveguide structures for integrated photonics (e.g. telecommu-nication) LNOI substrates (LNOI – lithium niobate on insulator) are used. Amorphous SiO2 or other glasses are feasible as insulator. The waveguiding requires an interlayer free connection of the wave-guide with the isolator. A difference in the coefficients of thermal expansion result in mechanical stresses within the substrates during bonding, which may lead to the destruction of the whole assembly. The resulting mechanical stresses can be evaluated by means of FEM (finite element modelling) or analytical approaches. By appropriate choice of the substrate materials and their geometry or prestressing of the substrates, stresses can be reduced. Aim of this thesis is the creation of a simu-lation tool for the bonding process and experimental verification of the substrate design to achieve minimal mechanical stress.

The open positions for this topic are offered in the research group Microstructure technology of apl.-Prof. Uwe D. Zeitner. The call will be open until position is filled. The full announcement and further contact information is given here. [pdf, 345 kb]

The Nano & Quantum Optics group at the Institute of Applied Physics targets to explore and understand the properties of nanoscale matter and objects and their interaction with photons. Currently two PhD positions are to be filled on the following topics under supervision of Prof. Thomas Pertsch: 

Applicants should keep a Master or Diploma in physics, photonics, electrical engineering, or comparable. For the project on plasmonic superfocusing applicants should have experimental experience as well as the motivation to develop and run complex laboratories. 

In addition, the Junior research group Quantum Optics is offering 2 PhD or Postdoc positions on Quantum Optics:

Applications are invited for candidates with a very good master’s degree in physics, optics, or a related disciplinea and a good understanding of quantum optics, integrated optics or light‐matter interaction, respectively. 

Please apply via the Online Application System of the Abbe School of Photonics. In your application, please make sure to inculde a clear statement on your preference concerning the PhD/postdoctoral project of your choice and/or your preferred supervisor. Any further questions, please feel free to contact the respective supervisor as given in the project descriptions.

The application deadline is January 31, 2022.
