The mid-infrared spectral range plays an increasingly important role in harnessing applications ranging from biodiagnostics to in-vivo sensing and food safety. This has led to the evolution of mid-infrared photonics from an emerging technology to an enabling tool in routine use catering to a wide range of real-world scenarios.
Applications ranging from non-invasive exhaled breath analysis to the in-vivo assessment of cartilage damage or the detection of mycotoxins in food and feed confirm mid-infrared (MIR; 3-20 μm) photonics among the most flexible molecular sensing platforms nowadays available. This development has been catalyzed by the emergence of quantum and interband cascade laser (QCL, ICL) and LED technology providing miniaturized laser light sources based on quantum heterostructures that may be combined with frequency-matched waveguides/transducers for on-chip hybridization and/or integration toward IR-lab-on-chip systems.
