“…In particular, we have reduced (or completely eliminated, in the case of fully symmetric deposit) the dependence of that response on the polarization of the incident light, thus permitting a major simplification in the design of the sensors. [6] Also, we can have multiple plasmon resonances with asymmetrically deposited DLUWTs, which we cannot obtain with for any other SPR transducers. [7] What we show in this paper is how the very concept of the DLUWT is instrumental to achieve a very important goal in SPR sensing, namely, to displace the plasmon resonance wavelength(s) to any desired region.…”

It is shown how the design possibilities offered by double-layer uniform-waist tapered optical fibers (DLUWTs) permit to move the wavelength detection range to adapt the response of the sensors to varied conditions. In particular, we have obtained very good experimental curves showing that we can achieve plasmon resonances in the C-band of the optical communications, around 1.5 μm, for the range of refractive indices of aqueous media, highly interesting in the biosensors field. Also, we show results for other interesting wavelength region, around 500 nm, where we can take advantage of the absorption peaks of the analytes. Finally, we explore the possibilities of using InN as a dielectric material for the second layer of the deposition. These results contribute to considerably expand the applicability and performance of SPR fiber sensors.

This work comprehends a review of nanostructured materials employed in the fabrication of optical fiber sensors in the last years. The continuous advances in nanofabrication techniques have enabled to manipulate the matter precisely producing well defined nanostructurated coatings or repetitive patterns at nanoscale level. The interactions of light with these nano-organized materials or patterns at the nanoscale level enable to observe interesting phenomena, such as interferometry, fluorescence, absorbance, resonances and many others which can be exploited in the fabrication of sensing devices. A particular case consists of optical fiber sensors, where the light travelling through an optical fiber interacts with the sensitive layer. The properties of the sensitive layer, such as the organization, physical properties, chemical bounds etc. will determine the sensing characteristics of the final device. The utilization of some of the most common nanostructured materials, such as polymers, nanoparticles, metals, metal oxides or biological coatings are reviewed here.

“…Generally, SPR-active films are prepared by vacuum evaporation or sputtering of the metals using expensive and complicated equipment. However, to ensure that the film around the curved surfaces of the optical fiber has a uniform thickness, specific rotation devices (Navarrete et al, 2010;Suzuki et al, 2008;Zhao et al, 2014) are required in the vacuum coating techniques. As another option for applying the metal nanofilm coating, electroless plating (ELP) is based on the chemical reduction of metal ions to deposit the metal onto the substrate.…”
