    Materials for the fabrication of optical fiber refractometers based on lossy mode resonance
    (2020) Ozcariz Celaya, Aritz; Ruiz Zamarreño, Carlos; Arregui San Martín, Francisco Javier; Ingeniería Eléctrica, Electrónica y de Comunicación; Ingeniaritza Elektrikoa, Elektronikoaren eta Telekomunikazio Ingeniaritzaren; Gobierno de Navarra / Nafarroako Gobernua
    Lossy mode resonances (LMR) have been studied as an exceptional phenomenon for the development of optical fiber refractometers. These sensors rely on the interaction of the light propagating through the waveguide with a thin-film fabricated onto it. The properties of such film will determine the sensitivity of the LMR to surrounding refractive index variations. The nature of the film will also play an important role on the possibilities to develop sensing applications. This thesis analyzes the use of four different materials (tin oxide, aluminum-doped zinc oxide, indium-gallium-zinc oxide and copper oxide) for the development of LMR-based refractometers. First, the optimization on the fabrication process of tin oxide coatings is described, with the purpose of maximizing the sensitivity in a refractive index range close of the fused silica (1.44). Then, materials based on zinc oxide are presented for the first time for the fabrication of LMR-based sensors: aluminum-doped zinc oxide (AZO) and indium-gallium-zinc oxide (IGZO), leading to the development of several sensors working in the visible and near-infrared wavelength range. The last material analyzed in this work is copper oxide, which presents a refractive index considerably larger than the previously studied materials. Such feature is suggested to provide a greater sensitivity of the LMR to SRI variations, promising a better performance than the one achieved with different thin-films.

    A comprehensive review: materials for the fabrication of optical fiber refractometers based on lossy mode resonance
    (MDPI, 2020) Ozcariz Celaya, Aritz; Ruiz Zamarreño, Carlos; Arregui San Martín, Francisco Javier; Ingeniaritza Elektrikoa, Elektronikoaren eta Telekomunikazio Ingeniaritzaren; Institute of Smart Cities - ISC; Ingeniería Eléctrica, Electrónica y de Comunicación; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, PJUPNA26
    Lossy mode resonance based sensors have been extensively studied in recent years. The versatility of the lossy mode resonance phenomenon has led to the development of sensors based on different configurations that make use of a wide range of materials. The coating material is one of the key elements in the performance of a refractometer. This review paper intends to provide a global view of the wide range of coating materials available for the development of lossy mode resonance based refractometers.

    Aluminum doped zinc oxide (AZO) coated optical fiber LMR refractometers. An experimental demonstration
    (Elsevier, 2019) Ozcariz Celaya, Aritz; Piña-Azamar, Dafne A.; Ruiz Zamarreño, Carlos; Domínguez Cruz, René; Arregui San Martín, Francisco Javier; Ingeniaritza Elektrikoa, Elektronikoaren eta Telekomunikazio Ingeniaritzaren; Institute of Smart Cities - ISC; Ingeniería Eléctrica, Electrónica y de Comunicación; Gobierno de Navarra / Nafarroako Gobernua
    This work presents the experimental demonstration of lossy mode resonance generation by means of aluminum doped zinc oxide thin-films. The use of such material may allow to optimize the performance of LMR-based sensors, obtaining good sensitivity at lower costs than other overlays, such as those including indium. The refractometric response of the fabricated devices is explored in different spectral regions. One refractometer working in the near infrared region was fabricated, obtaining a sensitivity of 2280 nm/RIU. A second refractometer working in the visible light spectrum was also fabricated. This second device allows to observe rough refractive index variations with the naked eye as a change of the color of the light propagating through the fiber, simplifying the setup needed for its use.

    Copper oxide coated D-shaped optical fibers for the development of LMR refractometers
    (IEEE, 2020) Ozcariz Celaya, Aritz; Vitoria Pascual, Ignacio; Arregui San Martín, Francisco Javier; Ruiz Zamarreño, Carlos; Ingeniaritza Elektrikoa, Elektronikoaren eta Telekomunikazio Ingeniaritzaren; Institute of Smart Cities - ISC; Ingeniería Eléctrica, Electrónica y de Comunicación; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, PJUPNA26
    Lossy mode resonance (LMR) based refractometers obtained by means of copper oxide thin-films fabricated onto side-polished (D-shaped) are presented in this work. The high refractive index of copper oxide combined with the propagation mode isolation capabilities of D-shaped fibers allows for the observation of narrow (30 nm) and high sensitive (10,336 nm per refractive index unit) LMRs, which could enable to improve the performance of LMR-based refractometers as well as provide an alternative label-free sensing platform for LMR-based sensors.
