High sensitivity lossy-mode resonance refractometer using low refractive index PFA planar waveguide
(Elsevier, 2023)
Artículo / Artikulua,
In this work a new strategy to improve the sensitivity of refractometers based on lossy-mode resonances has been proved. The proximity of the PFA (tetrafluoroethylene-perfluoro polymer) substrate refractive index to that ...
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 ...
Lossy mode resonance based 1-butanol sensor in the mid-infrared region
(Elsevier, 2023)
Artículo / Artikulua,
The utilization of nanometric Graphene Oxide / Polyethyleneimine (GO/PEI) bilayers deposited onto SnO2-coated CaF2 planar waveguides significantly enhances the sensitivity of Lossy Mode Resonances (LMR) based devices for ...
Tunable sensitivity in long period fiber gratings during mode transition with low refractive index intermediate layer
(IEEE, 2022)
Artículo / Artikulua,
Double-clad fibers where the second cladding has a lower refractive index than the first cladding, prove to be ideal structures for potentiating and tuning the sensitivity in long-period fiber gratings (LPFGs) operating ...
Ammonia gas optical sensor based on lossy mode resonances
(IEEE, 2023)
Artículo / Artikulua,
This letter presents the fabrication and characterization of an ammonia (NH 3) gas optical sensor based on lossy mode resonances (LMRs). A chromium (III) oxide (Cr 2 O 3) thin film deposited onto a planar waveguide was ...
Planar-waveguide-lmr-based sensors: engineering the depth of characteristic curves
(IEEE, 2023)
Artículo / Artikulua,
Lossy mode resonance (LMR)-based sensors have been proven as one of the exponentially growing research fields since the last decade. These sensors have demonstrated their capabilities in the detection of several physical, ...
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, ...
All-fiber ellipsometer for nanoscale dielectric coatings
(Chinese Academy of Sciences, 2023)
Artículo / Artikulua,
Multiple mode resonance shifts in tilted fiber Bragg gratings (TFBGs) are used to simultaneously measure the thickness and the refractive index of TiO2 thin films formed by Atomic Layer Deposition (ALD) on optical fibers. ...
Electrochemical lossy mode resonance for the detection of manganese ions
(Elsevier, 2023)
Artículo / Artikulua,
In this work we propose electrochemical lossy mode resonance (eLMR) as a powerful method for the detection of manganese (Mn) ions. The sensor is based on a simple planar waveguide (sodasingle bondlime glass coverslip) ...
