“…The sensitivity of RI needs improvement. Santos et al [18] presents the performance analysis of a new geometry sensing configuration for RI, based on SPR in photonic crystal fiber D-type optical fiber with a thin gold layer, using the finite element method. The sensitivity is high; however, photonic crystal fibers are expensive.…”

This study presents a facile, rapid and effective method for the fabrication of optical fiber surface plasmon resonance biosensors. A section of coreless fiber is spliced between two multimode fibers to construct a multimode-coreless-multimode (MCM) fiber structure. We take full advantage of the transmission characteristics of the coreless fiber, and the experimental results confirm that this MCM after coating with a thin gold film is able to excite surface plasmon wave effectively. Three sensors with different lengths of coreless optical fibers of 1 cm, 1.6 cm and 2 cm were constructed. And when the refractive index (RI) of the sucrose solution changes from 1.33 to 1.3883, the RI sensitivity was measured to be 2129.66 nm/RIU, 2249.33 nm/RIU and 2307.93 nm/RIU, respectively. After a comprehensive comparison, we chose the MCM optical fiber sensor with a coreless fiber length of 1.6 cm for biological experiments. After directly immobilized the antibody on the gold film, the biosensor was able to selective detect human immunoglobulin G (HIgG) with a sensitivity of 215 nm/ (mg ml −1 ). The limit of detection is 0.465 µg ml −1 . The biosensor exhibited effective antibody immobilization ability and high sensitivity for HIgG detection, which fully demonstrates its potential applications in the broader biomedical or chemical field.

“…a silver nanocolumn for refractive index sensing and achieved a maximum sensitivity of 8860 nm/RIU [6]. Recently, in order to provide a simple structure, Santos et al reported a suspended core optical fiber structure incorporating gold nanowire and achieved good sensitivity in comparison to the conventional single-mode fiber (SMF) [7]. In the same year, we have reported hollow core fiber (HCF) sensor consists of an AuNW and achieve an average sensitivity of 10560 nm/RIU for RI = 1.46-1.48 [8].…”

In this letter, we propose a novel approach to develop a highly sensitive surface plasmon resonance (SPR) based fiber optics biosensor. The sensor comprises a dual-drilled channel (DDC) with gold-nanowire (AuNW) contained in each channel to excite the plasmon modes. The SPR effect between the core guided mode and the surface plasmon polariton (SPP) modes of the DDC is used to evaluate the sensing response with respect to different analytes. The sensing performance, coupling characteristics, and the fabrication tolerance of the sensor are numerically analyzed and characterized by using a full-vectorial Finite Element Method (FEM). The designed sensor shows a minimum sensitivity of 3150 nm/RIU for refractive index (RI) = 1.310. While, the sensor exhibits an extremely high sensitivity varying from 10250 nm/RIU to 90500 nm/RIU for RI varied over the range of 1.370 to 1.400. Various structural parameters, e.g., separation of the channel from the core, the radius of the AuNW, the fabrication tolerance, etc., have been studied in this work. In addition, the possible fabrication steps of such a design have been discussed indicating its simple practical realization.

“…Waveguide modes in microstructured fibers are formed as a result of the interference of waves arising from reflection and refraction at the refractive-index microinhomogeneities [18]. In addition to the widespread photonic crystal fibers, in which several regular layers of air holes or glass rods are located around the core [16,26,28], there are suspended-core fibers, in which a thin core is surrounded by one row of air holes with thin walls between them [14,26,[29][30][31][32][33][34][35]. In addition, the manufacture of solid microstructured fibers from low-temperature chalcogenide and tellurite glasses simultaneously was reported [36].…”

High nonlinearity and transparency in the 1–5 μm spectral range make tellurite glass fibers highly interesting for the development of nonlinear optical devices. For nonlinear optical fibers, group velocity dispersion that can be controlled by microstructuring is also of great importance. In this work, we present a comprehensive numerical analysis of dispersion and nonlinear properties of microstructured two-, four-, six-, and eight-core tellurite glass fibers for in-phase and out-of-phase supermodes and compare them with the results for one-core fibers in the near- and mid-infrared ranges. Out-of-phase supermodes in tellurite multicore fibers are studied for the first time, to the best of our knowledge. The dispersion curves for in-phase and out-of-phase supermodes are shifted from the dispersion curve for one-core fiber in opposite directions; the effect is stronger for large coupling between the fields in individual cores. The zero dispersion wavelengths of in-phase and out-of-phase supermodes shift to opposite sides with respect to the zero-dispersion wavelength of a one-core fiber. For out-of-phase supermodes, the dispersion can be anomalous even at 1.55 μm, corresponding to the operating wavelength of Er-doped fiber lasers.
