Next-Generation Mid-Infrared Diagnostics

Prof. Dr. Boris Mizaikoff, Universit├Ąt Ulm, Inst. of Analytical and Bioanalytical Chemistry

Optical chemical sensors operating in the spectral range of 3-20 μm (mid-infrared) are gaining importance in a diversity of application areas ranging from process analysis, environmental monitoring, and security/ surveillance applications, to the biomedical and diagnostic field. The perspective of robust optical sensors providing inherent molecular specificity renders mid-infrared technology among the most promising sensor platforms for addressing complex samples in demanding measurement environments. Given the current advancements in light source technology (e.g., room-temperature operated broadly tunable quantum cascade lasers) and detectors, it appears of paramount importance developing appropriate mid-infrared transducers and waveguides to the same level of maturity for facilitating continuous and highly sensitive direct molecular analysis in the gas phase and in the liquid phase. Consequently, the advent of appropriate waveguide technology including mid-infrared transparent optical fibers, planar
