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 ...
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 ...
