TL;DR: In this article, a pH optical fiber sensor based on electromagnetic resonances generated in a waveguide-nanocoating interface is presented, where the incorporation of gold nanoparticles (AuNPs) into polymeric thin films has been deeply studied and the deposition of these thin-films onto an optical fiber core has been performed in order to obtain a resonance-based optical fiber device.

TL;DR: In this article, a thin-film consisting of 15 bilayers of titanium (IV) oxide and poly(sodium 4-styrenesulfonate) is simultaneously deposited onto two optical fiber structures: a singlemode--multimode--singlemode (SMS) device and a lossy mode resonance (LMR)-based device.

TL;DR: In this article, a novel fiber optic humidity sensor based on a functionally coated long-period fiber grating was proposed, which is composed of tetraorthosilicate matrix functionalized with perfluorooctyltriethioxysilane and its fabrication was performed by the solgel technique using a dip coating process using the LPG as substrate.

TL;DR: A theoretical analysis of an optical fiber photonic-bandgap-based refractometer is presented, based on a quarter-wave reflector with one defect, and some rules for the practical implementation of the refractometers are given.

TL;DR: This work will show a review about the SBS aim, the sensing architectures of optical fiber technology, and the opportunities that it has in this increasing market niche.
