Experimental demonstration shows a chalcogenide mid-infrared platform for detecting organic molecules in water, highlighting progress toward optical sensors.
Chalcogenide glasses have attracted attention for sensing applications due to their high transparency in the infrared range, their ability to be fabricated into thin films by PVD and to be processed into integrated photonic components by photolithography and etching. We will present the development of a chalcogenide-based mid-infrared platform dedicated to mid-infrared spectroscopy using evanescent waves. This study represents an important step towards the development of an optical sensor in the MIR spectral range using chalcogenide materials for the detection of organic molecules in water.
