Quantentechnologie

For my master thesis project I have set up, characterized, and tested a new fiber mirror production setup.

All technical elements have been interfaced with the lab computer and can be controlled with the same self-written program. All aspects influencing the ablation parameters and their control have been characterized to enable a predictable ablation sequence, and to identify aspects that require additional optimization.

Furthermore, I have set up an interference microscope to profile the produced ablation crater. In the process, I have implemented, tested, and compared several analysis methods. These routines have been integrated into the control software to enable feedback.

Finally, I have tested the setup on a fused silica substrate and on fiber end facets. From these tests it could be concluded that the setup is working as expected. Additionally, further information on its characteristics and necessary future steps could be gathered.
