We are excited to welcome Dr. Alexander Theis to the Laboratory of Lightwave Metrology!
Alex completed his PhD at Fraunhofer ITWM in close collaboration with RPTU, where his dissertation, “Design and Characterization of an Optoelectronic Laser Synchronization System for Spectrum and Network Analysis”, focused on the development of photonic measurement systems operating from the RF up to the terahertz range, enabling high resolution spectroscopy with single digit hertz level accuracy based on advanced optoelectronic laser synchronization.
His research expertise focuses on the modeling, implementation and metrological characterization of complex optoelectronic and photonic measurement setups, covering high frequency components such as waveguide and coaxial transmission lines as well as EMC related measurement scenarios. In addition, Alex develops advanced signal processing and evaluation routines for precision RF and terahertz measurements, including laser locking with optical phase locked loops for high resolution spectroscopy, and investigates nonlinear photonic effects such as four wave mixing in optical amplifiers.
In the team, Alex will initially take on the role of project coordinator for the relocation to the new laboratory, which will be jointly operated by RPTU and Fraunhofer. Thanks to his academic and institutional background, he represents an ideal interface between university and Fraunhofer research. Beyond this coordinating role, Alex will also contribute his scientific expertise to our mission to deepen the understanding of light matter interactions and to develop cutting edge photonic technologies for applications in material characterization, biology and medicine.
When he is not in the lab, Alex is a dedicated football player and a passionate strength training enthusiast. During the winter, he can often be found on the slopes as an avid snowboarder.
Welcome on board, Alex!
