En este trabajo de tesis se muestra el estudio y diseño de sensores basados en el fenómeno de la resonancia de modos con pérdidas en configuración de guía de onda plana, lo que supone un complemento para la plataforma habitual, la fibra óptica. Sus ventajas son la simplicidad de manejo y la robustez de los dispositivos desarrollados. En este sentido, se ha diseñado, sobre la base de la deposición de óxido de cobre (CuO) como material generador de la resonancia, sensores de humedad y de respiración, y sobre la base de la deposición de óxido de tungsteno (WO3), sensores de índice de refracción y de compuestos orgánicos como el etanol, el metanol y la acetona., This thesis work shows the study and design of sensors based on the phenomenon of lossy mode resonance in a planar waveguide configuration, which is a complement to the usual platform, optical fiber. Its advantages are the simplicity of use and the robustness of the devices developed. In this sense, it has been designed, based on the deposition of copper oxide (CuO) as a resonance generating material, humidity and respiration sensors, and based on the deposition of tungsten oxide (WO3), sensors for refractive index and organic compounds such as ethanol, methanol and acetone., Fondo de investigación PID2019-106231RB-I00 de la Agencia Estatal de Investigación española (AEI).

Los sensores basados en resonancias ópticas han incrementado su popularidad estos últimos años. Cobran especial relevancia en aplicaciones como la detección de gases gracias a su alta sensibilidad y robustez en ambientes agresivos.
Esta tesis ha contribuido a la mejora de sensores de gases basados en resonancias ópticas empleando dos enfoques; la búsqueda de materiales sensibles a gases y el desarrollo de nuevas técnicas de interrogación. Los materiales investigados están formados por una matriz polimérica con materiales nanoestructurados: nanopartículas de óxido tungsteno, nanodiamantes y nanosheets de óxido de grafeno. Las propiedades de estos materiales son testeadas ante diferentes gases e índices de refracción externo (surrouding refractive index SRI).
En la búsqueda de sensores ultrasensibles al SRI, se desarrollan dos líneas de investigación. Una estudia el efecto LMR y su sensibilidad en la región de infrarrojo medio (MIR) empleando fibras ópticas fluoradas y TiO2 como material. La otra, se centra en resonancias acuñadas por primera como surface exciton polariton resonance (SEPR) basándose en el efecto long range surface exciton polariton (LRSEP). Para ello se desarrolla un sensor en configuración Kretschmann-Raether con dos películas de Cr y MgF2. También se estudia los papeles de los distintos parámetros del sensor, así como experimentalmente la sensibilidad al ángulo de incidencia y SRI., Sensors based in optical resonances have increased their popularity in the last years. The ones used in gas measurement applications are especially relevant, due to their high sensitivity and robustness to harsh environments.
This thesis has contributed to the improvement of gas sensors based in optical resonances employing two approaches: the search for gas-sensitive materials and the development of new interrogation techniques. The researched materials are composed by a polymeric matrix and nanostructured materials: tungsten oxide nanoparticles, nanodiamonds and graphene oxide nanosheets. The properties of these materials are studied with different gas concentrations and surrounding refractive indexes (SRI).
Two research lines are developed to obtain ultrasensitive sensors to SRI. The first one studies the LMR effect and its sensitivity in the mid infrared (MIR) region, employing fluoride glass optical fibers and TiO2 as material. The second one focuses on the resonances coined for the first time as surface exciton polariton resonances (SEPR) that are based on the long range surface exciton polariton (LRSEP) effect. A sensor in a Krestchmann-Raether configuration is developed with two films of Cr and MgF2. The roles of the different parameters of the sensor are studied theoretically as well as the experimental sensitivity to the incident angle and SRI., Instituto de Smart Cities de la Universidad Pública de Navarra (Contratos Pre-doctorales adscritas a Grupos e Institutos de Investigación de la Universidad Pública de Navarra); Ministerio de Ciencia e Innovación (PID2019-106231RB-I00 TEC); Fondo Europeo de Desarrollo Regional (FEDER) (TEC2016-78047-R); convocatoria ATTRACT financiada por el programa de investigación e innovación Horizon 2020 de la Unión Europea (subvención No 777222); Universidad Pública de Navarra (PJUPNA26)., Programa de Doctorado en Ciencias y Tecnologías Industriales (RD 99/2011), Industria Zientzietako eta Teknologietako Doktoretza Programa (ED 99/2011)

The mode transition is a phenomenon observed in
thin film coated long period fiber gratings (LPGs) and singlemode multimode single-mode (SMS) fibers for certain values of
the coating thickness and refractive index, resulting in increased
sensitivity for sensing applications. It is shown here that mode
transitions occur simultaneously for a large number of mode
resonances in the transmission spectra of tilted fiber Bragg
gratings (TFBG) measured during the deposition of ~350nm thick
TiO2 coatings by Atomic Layer Deposition (ALD). In TFBGs, the
mode transition shows up as an acceleration of the resonance
wavelength shift vs thickness, but without fading of the resonance
amplitude. Furthermore, the results show that the mode transition
for cladding modes with predominantly “TE” polarization at the
cladding boundary is significantly sharper than that of
predominantly “TM” polarized modes and that it occurs at a
smaller coating thickness (<100 nm vs >200 nm). Finally, using a
separately determined coating refractive index (2.14, by
ellipsometry on witness flats deposited simultaneously) and
simulations of the resonance shifts of the TFBG with coating
thickness, it is demonstrated that a TFBG connected to a spectral
interrogation system can be used to measure the growth of a
coating on the surface of the fiber in real time., This work was supported in part by the Spanish Ministry, Formación de Profesorado Universitario under Grant FPU18/03087, in part by the Spanish

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 gas sensing applications. LMR generation in the mid-infrared region, which also contributed to achieve better sensitivities, was accomplished with the aid of fluorinated (CaF2) planar waveguides. LMR wavelength shift was studied as a function of the number of GO/PEI bilayers. In the particular case of 10 bilayers of GO/PEI, the sensitivity of the device to 1-butanol was 70.4 pm/ppm, which increased by a factor of 5 compared to the device without GO/PEI bilayers. The GO/PEI sensor was also sensitive to other alcohols, like 2-propanol, but it showed negligible sensitivity to other gases, such as CO2, NH3 or C2H2. The cross sensitivity with temperature was tested at temperatures of 20, 100 and 180 ºC during water vapor measurement (1723 ppm), showing that the sensor performance was not affected by the temperature fluctuations., This work was supported by Agencia Estatal de Investigación ( PID2019-106231RB-I00 ), Institute Smart Cities and Public University of Navarra Ph.D. Student grants.

Ethylene monitoring has long been a method of controlling the ripening of climacteric fruits, but it turns out that this gas is an important biomarker in biomedical applications. This work presents an optical gas sensor based on the lossy mode resonance (LMR) effect for ethylene detection in planar waveguide configuration. Two different approaches have been explored: one in the visible (VIS) spectral region and the second one in the mid infrared (MIR) region. Optical resonances have been achieved, in all cases, by means of sputtered tin oxide thin films. Response and recovery times were 54 and 246 s, respectively, for the sensor with the resonance in the VIS region, while the device operating in the MIR obtained response and recovery times of 19 and 47 s, respectively. The sensitivity during ethylene detection varied from 93.8 to 187.5 pm/ppm with the devices working in the VIS and MIR regions, respectively. According to the calibration curve, devices show an ethylene limit of detection (LOD) of 4.0058 and 0.6532 ppm in the VIS and MIR spectral regions, respectively, which finds applications in climacteric fruit ripening assessment as well as hemodialysis control. Cross sensitivity with humidity was also characterized for both devices., This work was supported by Agencia Estatal de Investigación under Grant PID2019-

Cyclic transparent optical polymer (CYTOP) fiber, used mainly in strain detection and refractive index characterization of liquids, can be polished for the detection of ultraviolet (UV) light radiation. The study investigates the transmission spectra of CYTOP fiber exposed to different intensities of UV light, demonstrating a linear relationship. A simplified system using a single wavelength, i.e., 395 nm, shows real-time performance of the sensor in a range from 1 to 15 mW. The results reveal the potential of CYTOP fiber as a UV sensor with a sensitivity of 0.65%/mW and a limit of detection of 0.3 mW, offering implications for monitoring UV radiation exposure and related health risks. In addition, the effect of the UV light was also observed at longer wavelengths with a lower intensity variation, which suggests that CYTOP fiber could be used for transmitting the UV radiation detection in telecommunications bands., This work was supported by the Spanish Agencia Estatal de Investigación (AEI) through Project PID2019-106231RB-I00.

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. This is achieved by comparing the experimental wavelength shifts of 8 TFBG resonances during the deposition process with simulated shifts from a range of thicknesses (T) and values of the real part of the refractive index (n). The minimization of an error function computed for each (n, T) pair then provides a solution for the thickness and refractive index of the deposited film and, a posteriori, to verify the deposition rate throughout the process from the time evolution of the wavelength shift data. Validations of the results were carried out with a conventional ellipsometer on flat witness samples deposited simultaneously with the fiber and with scanning electron measurements on cut pieces of the fiber itself. The final values obtained by the TFBG (n = 2.25, final thickness of 185 nm) were both within 4% of the validation measurements. This approach provides a method to measure the formation of nanoscale dielectric coatings on fibers in situ for applications that require precise thicknesses and refractive indices, such as the optical fiber sensor field. Furthermore, the TFBG can also be used as a process monitor for deposition on other substrates for deposition methods that produce uniform coatings on dissimilar shaped substrates, such as ALD., The authors would like to acknowledge the Spanish Ministry of Universities

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, hollow-core, and no-core mirror fibers. The sensor was tested on two different types of based metal, such as aluminum and steel, giving sensitivities as high as 38.7 and 5.75 nm/°C, respectively, showing good performance., This work was supported by the National Research Agency through Spanish project under Grant PID2019-106231RB-I00.

Two different thin film designs with a grating pattern are simulated on a soda lime coverslip, which acts as optical waveguide, with the purpose of generating both a lossy mode resonance (LMR) in transmission and reflection bands. This way both phenomena can be made sensitive to different parameters, leading to a multi-sensing device. The first design consists of a grating patterned in a SnO2 thin film deposited on the coverslip. The performance of the device in both transmission and reflection is numerically studied in air for different values of the grating pitch. Small grating pitches (in the order of the µm) are more suitable for generating the reflection bands while larger values (500 µm or more) are required to produce the LMR, when the reflection bands are no longer visible. Due to the inability to obtain both phenomena with this design, a second design is assessed, where the grating is combined with a section of constant thickness. In this case the desired response is obtained, which opens the path to use this device for multi-sensing applications, measuring several parameters at the same time., This research was funded by the Spanish Ministry of Universities (FPU18/03087 grant), and the Spanish Ministry of Economy and Competitiveness (PID2019-106231RB-I00 research fund).
