AbstractThe research presented in this cumulative thesis focuses on the development of mid-infrared (MIR) gas sensors based on optically highly efficient miniaturized IR absorption cells and their application in various sensing scenarios. The dissertation is based on five peer-reviewed journal articles, which were the result of an interdisciplinary research involving analytical chemistry, laser and optical engineering, physics, and medicine being conducted at the Institute of Analytical and Bioanalytical Chemistry at Ulm University. Within the framework of this thesis, absorption spectroscopy was combined with substrate- integrated hollow waveguides (iHWGs) for sensitive analysis of various molecules exhibiting distinctive infrared absorption features in the MIR spectral regime. There are two primary aims of the studies presented in this cumulative thesis: 1. Optimization of the performance of iHWGs as compact gas cells via testing of different substrate materials and coatings, fiber-coupling techniques and implementation of noise reduction techniques. 2. The development of compact sensor platforms that enable gas sensing in combination with newly developed infrared sources: A compact sensor combining iHWGs and surface-emitting ring quantum cascade lasers developed by the Vienna University of Technology with single-mode emission and symmetric low divergent beam profile was developed and tested. These QCLs offer highly collimated laser beams besides vertically emitting nature and are perfectly suitable for possible direct integration in iHWGs. A further contribution of this thesis is the development of gas sensors with novel MIR cascade lasers with very low power consumption. The so-called interband cascade lasers (ICL) enable continuous measurements of trace gases in the MIR range between 3 to 6 µm for various environmental, industrial, and biochemical sensing applications. An extensive study with main emphasis on the combination of ICLs and iHWGs was performed for the detection and quantification of methane in the ppm range within a compact sensor design. Moreover, within the scope of the EU-project Advanced Photonic SEnsor MAterials (APOSEMA), a new approach for laser based exhaled breath analysis utilizing dual-channel iHWGs and power-efficient ICLs was developed, prototyped, and tested for non-invasive continuous monitoring of CO2 and the isotope ratio of 13CO2/12CO2 in mouse breath. The developed sensor using laser based infrared spectroscopy allowed the integration of optochemical fluorescence sensors based on polymer nanofibers for ultra-fast oxygen sensing. The system was tested successfully for routine analysis in the mouse intensive care unit (MICU) at the Institute of Anesthesiologic Pathophysiology and Method Development. In summary, MIR sensing technologies developed within this dissertation indicate the high versatility of these iHWGs representing a key milestone in the development of compact sensor systems for fast and precise measurement of small volumes.dc.description.abstract
