Ammonia gas optical sensor based on lossy mode resonances
Armas, Dayron; Zubiate Orzanco, Pablo
; Ruiz Zamarreño, Carlos ; Matías Maestro, Ignacio (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 ... -
Bloch surface wave resonances generated with dielectric stack of high refractive index contrast deposited on a D-shaped optical fiber for sensing applications
Del Villar, Ignacio ; Kwietniewski, Norbert; Gonzalez-Valencia, Esteban; Burnat, Dariusz; Armas, Dayron; Pitula, Emil; Matías Maestro, Ignacio ; Chiavaioli, Francesco; Torres, Pedro; Smietana, Mateusz (Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena
A 5-layer stack composed of TiO2 and Al2O3, two materials with a high refractive index contrast, was deposited on a D-shaped fiber to generate Bloch surface wave resonances with an improved figure of merit. -
Enhancement of lossy mode resonance sensing properties by the introduction of an intermediate low-refractive-index layer
Armas, Dayron; Kwietniewski, Norbert; Matías Maestro, Ignacio ; Burnat, Dariusz; Śmietana, Mateusz; Del Villar, Ignacio (Optica, 2023)
Artículo / Artikulua
Devices based on the lossy mode resonance (LMR) effect have found numerous sensing applications. Herein, the enhancement of the sensing properties by the introduction of an intermediate layer between the substrate and the ... -
Generation of lossy mode resonances (LMR) using perovskite nanofilms
Armas, Dayron; Matías Maestro, Ignacio ; López-González, M. Carmen; Ruiz Zamarreño, Carlos ; Zubiate Orzanco, Pablo ; Del Villar, Ignacio ; Romero, Beatriz (Chinese Academy of Sciences, 2024)
Artículo / Artikulua
The results presented here show for the first time the experimental demonstration of the fabrication of lossy mode resonance (LMR) devices based on perovskite coatings deposited on planar waveguides. Perovskite thin films ... -
Micro sized interdigital capacitor for gases detection based on graphene oxide coating
Vitoria Pascual, Ignacio ; Armas, Dayron; Coronel Camones, Carlos Manuel; Algarra González, Manuel; Ruiz Zamarreño, Carlos ; Matías Maestro, Ignacio ; Mukhopadhyay, Subhas C. (Springer, 2023)
Contribución a congreso / Biltzarrerako ekarpena
A micro sized interdigital capacitor sensible to CO2 and NO is studied in this work. The photolithography technique enables to obtain fingers with dimensions of 10 × 500 µm and separated 7 µm between them. The deposition ... -
Micro sized interdigital capacitor for humidity detection based on agarose coating
Vitoria Pascual, Ignacio ; Armas, Dayron; Coronel Camones, Carlos Manuel; Ozcariz Celaya, Aritz ; Ruiz Zamarreño, Carlos ; Matías Maestro, Ignacio (2021)
Contribución a congreso / Biltzarrerako ekarpena
A micro sized interdigital capacitor has been proposed for the detection of relative humidity. The photolithography technique enables the fabrication of fingers with a size of 10x500 um. A thin film of agarose functionalizes ...
