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 ...
Optimized strain long-period fiber grating (LPFG) sensors operating at the dispersion turning point
(IEEE, 2018)
Artículo / Artikulua,
Two phenomena for enhancing the sensitivity of longperiod
fiber gratings are combined toward an increase of the sensitivity
to strain of this type of devices: the dispersion turning point
(DTP) and the cladding diameter ...
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 ...
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 ...
Sensors based on thin-film coated cladding removed multimode optical fiber and single-mode multimode single-mode fiber: a comparative study
(Hindawi Publishing Corporation, 2015)
Artículo / Artikulua,
Two simple optical fibre structures that do not require the inscription of a grating, a cladding removed multimode optical fibre
(CRMOF) and a single-mode multimode single-mode structure (SMS), are compared in terms of ...
Nanofabrication of phase-shifted Bragg gratings on the end facet of multimode fiber towards development of optical filters and sensors
(Elsevier, 2018)
Artículo / Artikulua,
This work describes the process of nanofabrication of phase-shifted Bragg gratings on the end facet of a
multimode optical fiber with a pulsed DC sputtering system based on a single target. Several structures
have been ...
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 ...
Wavelength and phase detection based SMS fiber sensors optimized with etching and nanodeposition
(IEEE, 2016)
Artículo / Artikulua,
The development of an optical fiber refractometer by
hydrogen fluoride etching and sputtering deposition of a thin-film
of indium tin oxide on a single-mode-multimode-single-mode fiber
structure has been analyzed with ...
Mode transition in complex refractive index coated single-mode–multimode–single-mode structure
(Optical Society of America, 2013)
Artículo / Artikulua,
By coating a single-mode–multimode–single-mode (SMS)
structure with a high refractive index thin-film it is possible to obtain a
transition of modes for specific combinations of thin-film thickness, thinfilm
refractive ...
