“…However, the fabrication of these structures is still expensive, which has severely limited their use to proof of concept and theoretical studies. In this sense, photonic crystal fibers (PCFs) have been extensively revised in theoretical works in literature using gold and silver, gold nanowires, gold multilayer with tantalum oxide, or titanium oxide among others.…”

Thanks to the peculiarities of optical fiber and its ability to be combined with nanotechnology, precise and accurate measurements of the changes in optical properties (i.e., refractive index) of the medium surrounding the fiber are becoming possible with a high degree of performance. Thus, optical fiber sensors (OFSs) are increasingly finding applications in biochemistry and biomedicine. Here, all types of optical fiber refractometers are covered, and they are classified into three main groups: interferometers, grating‐based structures, and resonance‐based structures (the resonance is induced by coating the optical fiber sensor with a thin film). The performance of these different structures is compared by means of the most common parameters: sensitivity, full width at half minimum or maximum, figure of merit, and quality factor. The aim here is to provide a reliable and easy‐to‐use tool to compare the performance of the most recent developments on fiber optic refractometers.

“…2 Modern medical research has additionally elucidated that implants having a porous tantalum coating upregulate osteogenic genes, resulting in greater osteointegration when compared to titanium implants without the coating. 3 Aside from applications in orthopedic implants, 4 tantalum and its sister niobium form oxides which have a variety of uses, including capacitors, 5 batteries, 6,7 electrochromic windows, 8 pH and conductivity sensors, [9][10][11][12][13] surface plasmon resonance sensors, [14][15][16] ferroelectric memory devices, [17][18][19][20] corrosion resistant coatings, 21 and even gravity wave detectors. 22 During manufacturing of such devices, production inefficiencies and waste material lead to the addition of a recycling step, 23 thereby complicating the fabrication of products containing tantalum.…”

“…Given that the incidence angle in the fiber core is denoted by θ i n , the reflectivity R s,p (θ i n ) from the multilayered cladding can be expressed as 7or (8). η cor e = n a cos θ i n and η out = n l cos θ out are for the TE waves, and η cor e = n a / cos θ i n and η out = n l / cos θ out are for the TM waves, where θ out is the refraction angle in the outermost layer.…”

“…The shift of the transmission spectrum with the RI of a liquid analyte filled in the air core or cladding of an MOF can be exploited as the sensing mechanism for RI measurements [3], [4]. In such an RI sensor, neither an elaborate preparation of microstructured devices [5], [6] nor an intricate coating of metal films on the surface of air holes [7], [8] is needed; hence, the fabrication difficulty is greatly reduced. However, the filling of a liquid analyte into holey MOFs (e.g., photonic crystal fibers) is time-consuming, severely restricting the response speed in real-time RI sensing.…”

Liquid-filled hollow core Bragg fibers (HCBFs) provide an excellent platform for refractive index (RI) sensing. The capacity for high-RI sensing based on higher order bandgaps of an HCBF is explored for higher sensitivity. We numerically compare the performances of an As 2 S 3 /PEI-based HCBF RI sensor using first-order and second-order photonic bandgaps (PBGs) for high-RI sensing. The influences of material dispersion and structural parameters on the sensing performance for both PBGs are investigated comparatively. Similar to the first-order PBG, the modification of the bandgap structure induced by material dispersion can also help to improve the linearity of an RI sensor using the second-order PBG of a conventional HCBF. For first-order and second-order PBGs including material dispersion, both a reduction in confinement loss and an improvement in sensitivity can be achieved by increasing the cladding period. In contrast, the influence of the period number on the sensitivity for a first-order PBG is contrary to that for a second-order PBG, which may be attributed to their different reflection characteristics. Furthermore, the comparative results show that a liquid-filled defect HCBF RI sensor using the second-order PBG can achieve high sensitivity and high linearity by optimizing the structural parameters of the defect layer. The proposed RI sensor would have great potential in the real-time measurement of high-RI liquid analytes.
