About this role
Our »Optical Quantum Metrology« research group develops innovative measurement technologies for clinical and industrial applications based on the ability to measure individual the oscillations of optical electric fields in the infrared and terahertz spectral ranges. As part of the Laboratory for Lightwave Metrology , the research group on the one hand offers the opportunity to fundamentally examine light at the quantum limit, and on the other hand to apply this knowledge in order to develop novel spectroscopic tools for medicine, biology and industrial material characterisation. The advertised PhD program aims to develop novel photonic measurement techniques based on interferometry and nonlinear optics that enable spectroscopic measurements of the entire physiologically relevant concentration range of molecules in biological fluids and gases. Achieving these ambitious goals requires substantial further development of key femtosecond technologies, which will be realised in the frame of a prestigious Max-Planck-Fraunhofer cooperation project. Selection of relevant publications: [1] I. Pupeza, et al., “Field-resolved infrared spectroscopy of biological systems“, Nature (2020) [2] P.
