“…To alleviate phase-matching problems of optical fiber-based SPR sensors, microstructured optical fiber (MOF)-based SPR sensors have been widely studied owing to their design flexibility [ 9 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ]. By changing the size, shape, and arrangement of air holes along the propagation direction, the n eff can be tuned to the anticipated values and thus can solve the phase-matching problem between the core mode and the SPP mode [ 9 , 15 , 16 , 17 , 24 , 25 ].…”

A surface plasmon resonance (SPR) sensor based on a dual-side polished microstructured optical fiber (MOF) with a dual core is proposed for a large analyte refractive index (RI; na) detection range. Gold is used as a plasmonic material coated on the polished surface, and analytes can be directly contacted with the gold film. The special structure not only facilitates the fabrication of the sensor, but also can work in the na range of 1.42–1.46 when the background material RI is 1.45, which is beyond the reach of other traditional MOF-SPR sensors. The sensing performance of the sensor was investigated by the wavelength and amplitude interrogation methods. The detailed numerical results showed that the proposed sensor can work effectively in the na range of 1.35–1.47 and exhibits higher sensitivity in the na range of 1.42–1.43.

“…Using a linear fitting, see the dashed line in Figure 5 b, we obtained a sensitivity value of

nm/RIU. In addition to large

values, our system exhibited higher performance than other recent proposals [ 51 , 52 , 53 ], as it can be noted from the figure of merit,

, shown in Figure 5 c. The partial results for the performance, resonant wavelengths,

, and

and R values are summarized in Table 1 , in comparison with their average values at the last row. Because several experimental approaches to develop these types of SPR-PCFs are available, though the experimental realization may be challenging, we expect that the ideas presented here will stimulate exploitation of multiple SPRs for sensing and multiband polarization filtering applications.…”

We investigate the plasmonic behavior of a fractal photonic crystal fiber, with Sierpinski-like circular cross-section, and its potential applications for refractive index sensing and multiband polarization filters. Numerical results were obtained using the finite element method through the commercial software COMSOL Multiphysics®. A set of 34 surface plasmon resonances was identified in the wavelength range from λ=630 nm to λ=1700 nm. Subsets of close resonances were noted as a consequence of similar symmetries of the surface plasmon resonance (SPR) modes. Polarization filtering capabilities are numerically shown in the telecommunication windows from the O-band to the L-band. In the case of refractive index sensing, we used the wavelength interrogation method in the wavelength range from λ=670 nm to λ=790 nm, where the system exhibited a sensitivity of S(λ)=1951.43 nm/RIU (refractive index unit). Due to the broadband capabilities of our concept, we expect that it will be useful to develop future ultra-wide band optical communication infrastructures, which are urgent to meet the ever-increasing demand for bandwidth-hungry devices.

“…MoSe 2 is regarded as the target combination in this case and the constant deposition will increase with a higher proportion of MoSe 2 , the given RI solution makes the fixed value of (dn/dc) ν . Then n d increases correspondingly according to (4), which leads to a larger shift of resonance wavelength and improvement of RI sensitivity. However, the deposition increases the thickness of the layer and also reduces the overlap between the analyte layer and the evanescent field.…”

“…The sensitivity increases first and then decreases. This can also be explained using (4), where the BSA is the analyte with a fixed concentration. In other words, as BSA accumulates and the thickness of MoSe 2 increases, the ionization intensity of the evanescent field is not strong enough to break down the dielectric medium and to excite the SPR phenomenon.…”

Surface Plasmon resonance (SPR) provides an efficacious and label-free detection method for optical fiber bio-sensing. MoSe 2 is one of the transition metal dichalcogenides (TMDCs) which has broad applications in detecting specific reactions. Cysteamine hydrochloride with enriched groups can generate self-assemble films for tight attachment. In this study we aimed to combine the rapid response of optical fiber SPR sensors with the enhanced sensitivity of MoSe 2 nano-films. An optical fiber SPR biosensor with MoSe 2-Au nanostructure was proposed and implemented, and a sensitivity of 2821.81 nm/RIU was achieved, which was approximately 98.7% higher than that of conventional SPR sensor without using MoSe 2 nanostructure. Furthermore, Bovine Serum Albumin (BSA) was utilized as the target molecule to test the bioaffinity of the biosensor with MoSe 2 deposition cycles from 0 to 8. Weighing the sensitivity and the figure of merit (FOM), the best deposition cycle of MoSe 2 was 4 with the sensitivity of 2793.36 nm/RIU and FOM of 37.24 RIU −1. At last, immunization experiments were carried out using Goat-anti-Rabbit IgG and a detection limit of 0.33 µg/mL was achieved. The rapid response and the high bioaffinity showed a strong applicability of the proposed MoSe 2-Au SPR immune-sensor in specific interactions and immunization therapy.
