University of Stuttgart (5th Institute of Physics) in cooperation with Q.ANT GmbH

Within the IQST Graduate School framework, the hot atomic vapor spectroscopy group at the 5th Institute of Physics is currently seeking a PhD student. This PhD program is in close collaboration with Q.ANT GmbH in Stuttgart, a deep-tech company that develops photonic computing and photonic sensing products.

The goal of this project is the development of highly integrated vapor cells with 3D optical access for more advanced spectroscopy schemes. These vapor cells will be the core component in atomic gyroscope and magnetometer products being developed at Q.ANT.

For fabricating such versatile cells we will rely on laser-assisted glass-etching, laser-welding as well as laser-written waveguide structures and polarization optics. This part of the project will be implemented together with the laser-based material processing experts at the Institut für Strahlwerkzeuge (IFSW) at the University of Stuttgart.

The fabricated gas-filled cells will then be investigated in the 5th Institute of Physics by various spectroscopy schemes and also at Q.ANT in their gyroscope/magnetometer labs.

With this thesis, the PhD student will acquire broad knowledge on state-of-the-art laser technology, on fundamental aspects of atomic spectroscopy and quantum physics, and will finally learn how to develop a commercial quantum sensor.

Your role:

Basic research in the theory and experiments with hot atomic vapors.
Develop advanced 3D vapor cell specifications to be manufactured at IFSW.
Investigate and characterize the properties of the 3D vapor cells using various laser spectroscopy methods.
Validation of the 3D vapor cells in quantum sensor applications at Q.ANT (atomic gyroscopes and magnetometers).
