Sensitivity enhancement in low cutoff wavelength long-period fiber gratings by cladding diameter reduction
(MDPI, 2017)
Artículo / Artikulua,
The diameter of long-period fiber gratings (LPFGs) fabricated in optical fibers with a low cutoff wavelength was be reduced by hydrofluoric acid etching, enhancing the sensitivity to refractive index by more than a factor ...
Recent developments in fiber optics humidity sensors
(MDPI, 2017)
Artículo / Artikulua,
A wide range of applications such as health, human comfort, agriculture, food processing and storage, and electronic manufacturing, among others, require fast and accurate measurement of humidity. Sensors based on optical ...
Spectral shadowing suppression technique in phase-OTDR sensing based on weak fiber Bragg grating array
(Optical Society of America, 2019)
info:eu-repo/semantics/article,
A postprocessing procedure is presented to suppress spectral shadowing in phase-OTDR sensing systems based on a weak fiber Bragg grating array. A complete theoretical analysis of the interfering signals has been carried ...
Sensitivity optimization with cladding-etched long period fiber gratings at the dispersion turning point
(Optical Society of America, 2016)
Artículo / Artikulua,
This work presents a refractive index sensor based on a long period fiber grating
(LPFG) made in a reduced cladding fiber whose low order cladding modes have the turning
point at large wavelengths. The combination of ...
Tunable SESAM-based mode-locked soliton fiber laser in linear cavity by axial-strain applied to a FBG
(IEEE, 2017)
info:eu-repo/semantics/article,
A self-started stable tunable mode-locked (ML) soliton fiber laser in a linear cavity structure composed by commercial passive elements is presented in this paper. It is based on the combination of an Erbium doped fiber ...
