Monitoring the etching process in LPFGs towards development of highly sensitive sensors
(MDPI, 2017) Contribución a congreso / Biltzarrerako ekarpena,
In this work, the monitoring of the etching process up to a diameter of 30 µm of two LPFG structures has been compared, one of them had initially 125 µm, whereas the second one had 80 µm. By tracking the wavelength shift ...
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 ...
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 ...
Label-free wavelength and phase detection based SMS fiber immunosensors optimized with cladding etching
(Elsevier, 2018) Artículo / Artikulua,
The performance of E-SMS (Etched Singlemode-Multimode-Singlemode) optical fiber structures as immunosensors has been assessed by the implementation of antibody/antigen immunoassays. Through this procedure it has been ...
