Journal ArticleDOI
Enhancement of sensitivity in long-period fiber gratings with deposition of low-refractive-index materials.
TL;DR: It was proved that the deposition of an overlay of higher refractive index than that of the cladding of the LPFG causes large shifts in the attenuation bands induced by the grating, and it is proved that, if the second overlay is thick enough, its behavior resembles that of an infinite layer.
Journal ArticleDOI
Micro and Nanostructured Materials for the Development of Optical Fibre Sensors.

TL;DR: This review reveals some of the main techniques that are currently been employed to develop this kind of sensors, describing in detail both the resulting supporting matrices as well as the sensing materials used.
Journal ArticleDOI
Dual-Peak Resonance-Based Optical Fiber Refractometers
Carlos R. Zamarreño,P. Sanchez,Miguel Hernaez,Ignacio Del Villar,Carlos Fernández-Valdivielso,Ignacio R. Matias,Francisco J. Arregui +6 more
TL;DR: In this paper, the authors presented the fabrication of optical fiber refractometers by means of the deposition of a thin indium-oxide coating onto an optical fiber core, creating resonances in the infrared and visible regions.
Journal ArticleDOI
Optimization in nanocoated D-shaped optical fiber sensors
TL;DR: Nanocoated D-shaped optical fibers have been proven as effective sensors and the full width at half minimum (FWHM) of lossy mode resonance can be reduced by optimizing the nanocoating width, thickness and refractive index.
Journal ArticleDOI
Lossy mode resonance sensors based on lateral light incidence in nanocoated planar waveguides
TL;DR: The sensors presented here open up the path for the development of LMR-based chemical sensors, environmental sensors, biosensors, or even the generation of other optical phenomena with the deposition of multilayer structures, gratings or nanostructures, which is much easier in a planar waveguide than in an optical fibre.
