    • Generation of lossy mode resonances in planar waveguides toward development of humidity sensors 

      Fuentes Lorenzo, Omar Upna; Corres Sanz, Jesús María Upna Orcid; Matías Maestro, Ignacio Upna Orcid; Del Villar, Ignacio Upna Orcid (IEEE, 2019)   Artículo / Artikulua  OpenAccess
      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, ...
    • Generation of lossy mode resonances with different nanocoatings deposited on coverslips 

      Fuentes Lorenzo, Omar Upna; Goicoechea Fernández, Javier Upna Orcid; Corres Sanz, Jesús María Upna Orcid; Del Villar, Ignacio Upna Orcid; Ozcariz Celaya, Aritz Upna Orcid; Matías Maestro, Ignacio Upna Orcid (Optical Society of America, 2020)   Artículo / Artikulua  OpenAccess
      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 ...
    • Improving the width of lossy mode resonances in a reflection configuration D-shaped fiber by nanocoating laser ablation 

      Fuentes Lorenzo, Omar Upna; Vaiano, Patrizio; Del Villar, Ignacio Upna Orcid; Corres Sanz, Jesús María Upna Orcid; Matías Maestro, Ignacio Upna Orcid (Optical Society of America, 2020)   Artículo / Artikulua  OpenAccess
      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 ...
    • Interdigital concept in photonic sensors based on an array of lossy mode resonances 

      Domínguez Rodríguez, Ismel Upna Orcid; Del Villar, Ignacio Upna Orcid; Fuentes Lorenzo, Omar Upna; Corres Sanz, Jesús María Upna Orcid; Matías Maestro, Ignacio Upna Orcid (Nature Research, 2021)   Artículo / Artikulua  OpenAccess
      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 ...
    • Lossy mode resonance sensors based on lateral light incidence in nanocoated planar waveguides 

      Fuentes Lorenzo, Omar Upna; Del Villar, Ignacio Upna Orcid; Corres Sanz, Jesús María Upna Orcid; Matías Maestro, Ignacio Upna Orcid (Nature Research, 2019)   Artículo / Artikulua  OpenAccess
      The deposition of an indium oxide (In2O3) thin film on conventional planar waveguides (a coverslip and a glass slide) allows generating lossy mode resonances (LMR) by lateral incidence of light on the waveguide and by ...
    • Multichannel refractometer based on lossy mode resonances 

      Fuentes Lorenzo, Omar Upna; Corres Sanz, Jesús María Upna Orcid; Domínguez Rodríguez, Ismel Upna Orcid; Del Villar, Ignacio Upna Orcid; Matías Maestro, Ignacio Upna Orcid (IEEE, 2022)   Artículo / Artikulua
      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 ...
    • Optical fiber vacuum sensor based on etched SMS structure and PDMS coating 

      Ascorbe Muruzabal, Joaquín Upna Orcid; Fuentes Lorenzo, Omar Upna; Arregui San Martín, Francisco Javier Upna Orcid; Matías Maestro, Ignacio Upna Orcid; Corres Sanz, Jesús María Upna Orcid (IEEE, 2020)   Artículo / Artikulua  OpenAccess
      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 ...
