Increasing the sensitivity of an optic level sensor with a wavelength and phase sensitive single-mode multimode single-mode (SMS) fiber structure
(IEEE, 2017) Artículo / Artikulua,
The sensitivity of a liquid level sensor based on a single-mode-multimode-single-mode fiber structure has been increased by hydrofluoric acid etching. The etching process was analyzed and monitored both theoretical and ...
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 ...
Optimization of sensors based on multimode interference in single-mode–multimode– single-mode structure
(IEEE, 2013) Artículo / Artikulua,
By coating a single-mode–multimode–single-mode (SMS) structure with a complex refractive index thin-film the central wavelength of the transmission and attenuation bands of the optical spectrum can be shifted. By adequate ...
