Development of a detector based on silicon-integrated Mach Zehnder interferometers for the analysis of volatile organic compounds by gas chromatography
Gas chromatography (GC) is a reference technique in gas analysis. Nowadays, the growing need for on-site gas chromatography for healthcare and industry is pushing scientists towards miniaturization of the system. Detector miniaturization is part of this effort. Among the miniaturized detectors, which have been developed so far, the compactness, high multiplexing capabilities and low fabrication cost of integrated photonic detectors are promising. In this context, this work proposed the use of integrated Mach Zehnder interferometers (MZI) as GC detectors. After a proof of concept detection of GC-separated analytes, we explored possibilities of performance enhancement such as a detector's sensitivity. An exploratory study of the coupling of a GC to a functionnalized MZI matrix is also brought forward.
