Friedrich Schiller University is a traditional university with a strong research profile rooted in the heart of Germany. As a university covering all disciplines, it offers a wide range of subjects. Its research is focused on the areas Light—Life—Liberty. It is closely networked with non-research institutions, research companies and renowned cultural institutions. With around 18,000 students and more than 8,600 employees, the university plays a major role in shaping Jena’s character as a cosmopolitan and future-oriented city.

We offer a limited full-time postdoctoral position (40 hours/week) or a part-time doctoral position (75%, 30 hours/week), (initially) limited until 30th Juni 2025, with the possibility of an extension if appropriate.
The Institute of Applied Physics (IAP) focuses on basic and applied research in the fields of micro- and nano optics, fiber- and waveguide optics, ultrafast optics, quantum optics and optics. The possibility of doing a PhD is possible within the research group Microstructure Technology.
Research theme: 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 position is limited with the possibility of an extension if appropriate.
This is a full-time position (40 hours per week) for postdocs or a part-time position with 75% of the working hours of a full-time employee (30 hours per week) for PhD candidates.
Candidates with severe disabilities will be given preference in the case of equal qualifications and suitability.
