Master's thesis (m/f/x) - Design of a diode laser (Hamburg)

Job description

At the DLR Institute of Quantum Technologies in Ulm, we develop precision instruments for space applications based on quantum technologies and bring them to prototype maturity together with industry. In addition, we are driving forward the transfer to aeronautics, digitalisation, energy, security and transport. We have an interdisciplinary approach: Theoretical basic research and experimental tests meet engineering implementation. What to expect The Department for the Integration of Micro- and Nano-systems (QT-IMN) develops technologies for the implementation and miniaturization of quantum systems. In particular, the challenging requirements of the aerospace industry are taken into account and possibilities to increase the scalability of the systems are explored. At our Hamburg-Lokstedt site, we collaborate with start-ups that are developing ion-trap-based quantum computers for the German Aerospace Center (DLR). As part of this collaboration, we develop and characterize chip-based optical waveguides for our project partners. The objective of this position is to set up and characterize diode lasers. These lasers will be used to upgrade an existing measurement system for determining the intrinsic losses of optical waveguides by enabling measurements at additional wavelengths. Your tasks You assemble and characterize diode lasers from provided components. The diode lasers are designed to emit light at wavelengths of 935 nm and 780 nm. You continuously optimize and further develop the scattered-light measurement technique and the insertion-loss method for characterizing the intrinsic losses of optical waveguides. You determine the intrinsic losses of in situ fabricated optical waveguides. You develop software to control the individual system components and to automate the experiments described above. You contribute to the further development of our control software. Your profile Student in a scientific university degree program (Bachelor’s or Master’s) in natural sciences (e.g., Physics, Chemistry) or natural sciences or engineering (Electrical Engineering, Information Systems) or other degree programs relevant to the position first Knowledge of microsystems engineering, of atomic, molecular, or laser physics and in creating graphical user interfaces in Python or LabVIEW Unfortunately, it is not possible to offer remuneration for the completion of the Master’s thesis. There may be an opportunity to work as a student assistant in a related field. Remuneration for this role, depending on qualifications and the tasks assigned, may be up to pay band E5 of the TVöD as part-time work. We look forward to getting to know you!
