TL;DR: In this paper, the numerical and experimental analysis on the use of thinned fiber Bragg gratings as refractive index sensors have been carried out, where wet chemical etching in a buffered hydrofluoric acid solution was used for sensor fabrication.

TL;DR: The numerical and experimental investigation of the cladding modes re-organization in high refractive index (HRI) coated Long Period Gratings (LPGs) is reported, leading to relevant improvements in the SRI sensitivity in terms of wavelength shift and amplitude variations of the LPGs attenuation bands.

TL;DR: This work proposes a reliable fabrication process enabling the integration of dielectric and metallic nanostructure on the tip of optical fibers, thus representing a further step in the "lab-on-fiber" technology roadmap and demonstrates a first technological platform based on the integration onto the optical fiber tip of two-dimensional hybrid metallo-dielectric nanostructures supporting localized surface plasmon resonances.

TL;DR: In this paper, the authors present an overview of the Lab on Fiber technologies and devices with special focus on the design and development of advanced fiber optic nanoprobes for biological applications and discuss the strategies, main achievements and related devices developed in the “Lab on Fiber roadmap.

TL;DR: In this article, a novel approach based on the selective etching along the grating region has been analyzed, leading to high-sensitivity refractive index sensors based on intensity measurements.
