“…To date, successful demonstrations of fiber optic sensors utilizing metal oxides are realized by thin film coatings as in this domain the index compatibility issues can be mitigated [16][17][18][19][20][21][22][23][24][25][26][27]. Sensory materials such as metal oxides can be coated on D-shaped fiber, side polished fiber, or simply coated on the fiber cladding and can be combined with fiber Bragg gratings or long period gratings [17,18,20].…”

This paper presents an effective integration scheme of nanostructured SnO 2 with the fiber optic platform for chemical sensing applications based on evanescent optical interactions. By using a triblock copolymer as a structure directing agent as the means of nano-structuring, the refractive index of SnO 2 is reduced from >2.0 to 1.46, in accordance with effective medium theory for optimal on-fiber integration. Hightemperature stable fiber Bragg gratings inscribed in D-shaped fibers were used to perform real-time characterization of optical absorption and refractive index modulation of metal oxides in response to NH 3 from the room temperature to 500°C. Measurement results reveals that the redox reaction of the nanostructured metal oxides exposed to a reactive gas NH 3 induces much stronger changes in optical absorption as opposed to changes in the refractive index. Results presented in this paper provide important guidance for fiber optic chemical sensing designs based on metal oxide nanomaterials. ©2014 Optical Society of America References and links1. S.

“…В оптических сенсорах нет таких ограничений; при этом измерения оптических характеристик, таких как коэффициент пре-ломления или поглощения света [4,5] позво-ляют с хорошей точностью определять кон-центрацию взрывоопасных газов за счет уве-личения оптического пути прохождения света [3,5]. Использование нескольких селективных к тому или другому газу материалов, нанесен-ных на световод или прозрачную подложку, которые изменяют параметры световых лучей (их спектральный состав, или интенсивность) в определенном участке оптического спектра, создает основу для разработки оптических мультисенсоров взрывоопасных (водород) и токсичных (угарный газ) газов в воздухе.…”

“…In some cases, they are necessarily supported by the use of a transducer coating on the fiber [12,[25][26][27][28][29][30][31], therefore lacking of an intrinsic chemical sensitivity. In these setups, the coating is delegate to perform the actual chemical detection, whereas the fiber sensor is aimed to quantify the change in a certain optical property of the fiber triggered by the transducer.…”

Abstract: Chemical sensing using optical fibers is often challenging, as it is generally difficult to achieve strong interaction between the guided light and the analyte at the wavelength of interest for performing the detection. Despite this difficulty, many schemes exist (and can be found in the literature) for point chemical fiber sensors. However, the challenge increases even further when it comes to performing fully distributed chemical sensing. In this case, the optical signal which interacts with the analyte is typically also the signal that has to travel to and from the interrogator: for a good sensitivity, the light should interact strongly with the analyte, leading inevitably to an increased loss and a reduced range. Few works in the literature actually provide demonstrations of truly distributed chemical sensing and, although there have been several attempts to realize these sensors (e.g. based on special fiber coatings), the vast majority of these attempts has failed to reach widespread use due to several reasons, among them: lack of sensitivity or selectivity, lack of range or resolution, cross sensitivity to temperature or strain, or need to work at specific wavelengths where fiber instrumentation becomes extremely expensive or unavailable. In this work we provide a preliminary demonstration of the possibility of achieving distributed detection of gas presence with spectroscopic selectivity, high spatial resolution, potential for long range measurements and feasibility of having most of the interrogator system working at conventional telecom wavelengths. For a full exploitation of this concept, new fibers (or more likely, fiber bundles) should be developed capable of guiding specific wavelengths in the IR (corresponding to gas absorption wavelengths) with good overlap with the analyte while also having a solid core with good transmission behavior at 1.55 µm, and good thermal coupling between the two guiding structures.
