Sensitivity analysis of bent sensing elements of the fiber probes for mid-IR spectroscopy
Remote analysis of the chemical composition of various substances in real time is a pressing problem. Current development of the fiber based evanescent wave spectroscopy (FEWS) in the mid-infrared range meets modern industrial, environmental, safety and medical needs. This paper presents a sensitivity analysis of the fiber probes for FEWS based on bent chalcogenide fibers as sensing elements. A previously developed methodology is applied to study the sensitivity of bent fiber tapers and bent fibers of constant diameter immersed in a liquid analyte. The wave optics based approach is used in calculations of the attenuation coefficients of the bend modes in the COMSOL Multiphysics solver. For evaluation of the bent fiber taper transmittance, the method of local modes is applied. The sensitivity analysis is carried out for the probes made of chalcogenide fibers of Ge20Se80 composition immersed in an aqueous solution of isopropyl alcohol with concentrations of 0 to 50 vol.%. The results of FEWS measurements with the U-shaped fiber taper of a certain geometry are used for assessment of the analysis outcomes. The role of light launching conditions in the operation of a fiber probe is discussed.
