Ultrahigh-sensitivity sensors based on thin-film coated long period gratings with reduced diameter, in transition mode and near the dispersion turning point
(Optical Society of America, 2015) Artículo / Artikulua,
The mode transition and the dispersion turning point have been explored for optimization of thin-film coated long period fiber gratings during the last years. In this work and additional parameter, the cladding diameter, ...
Optimization in nanocoated D-shaped optical fiber sensors
(Optical Society of America, 2017) Artículo / Artikulua,
Nanocoated D-shaped optical fibers have been proven as effective sensors. Here, we show that the full width at half minimum (FWHM) of lossy mode resonance can be reduced by optimizing the nanocoating width, thickness and ...
Refractometric sensors based on multimode interference in a thin-film coated singlemode– multimode–single-mode structure with reflection configuration
(Optical Society of America, 2014) Artículo / Artikulua,
Thin-film coated single-mode–multimode–single-mode (SMS) structures have been analyzed both theoretically and experimentally with the aim of detecting different refractive indices. By adequate selection of the thickness ...
Mode transition in complex refractive index coated single-mode–multimode–single-mode structure
(Optical Society of America, 2013) Artículo / Artikulua,
By coating a single-mode–multimode–single-mode (SMS) structure with a high refractive index thin-film it is possible to obtain a transition of modes for specific combinations of thin-film thickness, thinfilm refractive ...
