Highly sensitive sensor for measuring material thermal expansion using a ring laser
(IEEE, 2023)
Artículo / Artikulua,
A new thermal expansion sensor is presented in this letter. It combines an interferometric fiber sensor and an erbium-doped fiber ring laser as the light source. The sensor consists of a combination of single-mode, ...
Improving the width of lossy mode resonances in a reflection configuration D-shaped fiber by nanocoating laser ablation
(Optical Society of America, 2020)
info:eu-repo/semantics/article,
The full width at half maximum (FWHM) of lossy mode resonances (LMRs) in the optical spectrum depends on the homogeneity of the thin film deposited. In this Letter, a method for improving the FWHM is applied for an LMR ...
Optical fiber vacuum sensor based on etched SMS structure and PDMS coating
(IEEE, 2020)
info:eu-repo/semantics/article,
In this work, an optical fiber vacuum sensor based on a single-mode multimode single-mode (SMS) structure coated with polydimethylsiloxane (PDMS) is studied. The SMS structure generates an interferometric pattern based on ...
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 ...
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 ...
Interdigital concept in photonic sensors based on an array of lossy mode resonances
(Nature Research, 2021)
Artículo / Artikulua,
Multi-parameter detection is key in the domain of sensors. Here it is demonstrated that an indium tin oxide (ITO) nanocoating can be used to generate multiple lossy mode resonances (LMRs) in the optical spectrum. To achieve ...
Simultaneous generation of surface plasmon and lossy mode resonances in the same planar platform
(MDPI, 2022)
info:eu-repo/semantics/article,
A planar waveguide consisting of a coverslip for a microscope glass slide was deposited in one of its two faces with two materials: silver and indium tin oxide (ITO). The incidence of light by the edge of the coverslip ...
Generation of lossy mode resonances with different nanocoatings deposited on coverslips
(Optical Society of America, 2020)
info:eu-repo/semantics/article,
The generation of lossy mode resonances (LMRs) with a setup based on lateral incidence of light in coverslips is a simple platform that can be used for sensing. Here the versatility of this platform is proved by studying ...
Multichannel refractometer based on lossy mode resonances
(IEEE, 2022)
info:eu-repo/semantics/article,
In this work a new multiparameter sensor platform based on lossy mode resonances is presented. The structure consists of a soda-lime optical slab waveguide butt-coupled to multimode optical fibers. A variable thickness ...
Generation of lossy mode resonances in planar waveguides toward development of humidity sensors
(IEEE, 2019)
info:eu-repo/semantics/article,
Lossy mode resonances (LMRs) are typically obtained with optical fibre. The Kretschmann configuration is an alternative but LMRs are generated with angles approaching grazing incidence. In this work, a new setup is explored, ...
