Long period fiber gratings with overlay of variable refractive index
(IEEE, 2005) Artículo / Artikulua,
A theoretical analysis is presented of a long-period fiber grating (LPFG) with an overlay of variable refractive index. The highest sensitivity of the resonance wavelengths to variations in the refractive index of the ...
Fiber-optic nanorefractometer based on one-dimensional photonic-bandgap structures with two defects
(IEEE, 2004) Artículo / Artikulua,
A theoretical analysis of a fiber-optic photonic- bandgap (PBG)-based nanorefractometer is presented. Changes up to 11.2 dB in the optical output power in an index of refraction range of 1.7 with a sensitivity of 1.5 ...
Etched LPFGs in reflective configuration for sensitivity and attenuation band depth increase
(IEEE, 2016) Artículo / Artikulua,
A reflection configuration setup for long-period fiber gratings is presented. It permits to obtain a unique band with attenuation double than that obtained in transmission configuration, which is interesting for ...
Spectral evolution with incremental nanocoating of long period fiber gratings
(Optical Society of America, 2006) Artículo / Artikulua,
The incremental deposition of a thin overlay on the cladding of a long-period fiber grating (LPFG) induces important resonance wavelength shifts in the transmission spectrum. The phenomenon is proved theoretically with ...
Deposition of coatings on long-period fiber gratings: tunnel effect analogy
(Springer, 2006) Artículo / Artikulua,
The sensitivity of Long-period fiber gratings (LPFGs), coated with high-refractive-index thin film overlays, to the refractive index and the thickness of the overlay, and to the ambient refractive index, can be enhanced ...
Fringe generation with non-uniformly coated long-period fiber gratings
(Optical Society of America, 2007) Artículo / Artikulua,
In this work, the spectral characteristics of non-uniform symmetrically ring shaped coatings deposited on long-period fiber gratings (LPFGs) have been theoretically and experimentally investigated. To optimize the ...
