Abstract

Fiber-based evanescent wave spectroscopy in the mid-IR is a powerful tool for the remote chemical analysis of liquids and gases in real time. Design of a sensing element of the fiber sensor is important for optimization of its output characteristics. In addition to unclad chalcogenide fibers that were previously used as the sensing elements, we consider core-clad fibers consisting of a multimode core and a ring cladding with the refractive index greater than that one of the core. For numerical analysis, a theoretical approach based on electromagnetic theory of optical fibers has been used. Calculated transmittance of the sensing elements is compared with the measured output characteristics of a sensing element made of an unclad chalcogenide fiber, which was immersed into aqueous acetone solutions.
