    • Characterization of microring filters for differential group delay applications 

      Doménech, D.; Chamorro Posada, P.; Fraile Pelaez, F.J.; Erro Betrán, María José Upna; Tainta Ausejo, Santiago Upna; Muriel, M. A.; Baños, R.; Bolten, J.; Kleinjans, H. (IEEEOptical Society of America, 2017)   Artículo / Artikulua  OpenAccess
      The longitudinal offset technique permits to improve the accuracy of the coupling coefficients of integrated directional couplers and provides designs that can be easily implemented with current fabrication tolerances. ...
    • Modulated fiber ring laser and its application in high-sensitivity temperature sensors 

      Pérez Herrera, Rosa Ana Upna; Tainta Ausejo, Santiago Upna; Erro Betrán, María José Upna; López-Amo Sáinz, Manuel Upna (SPIE, 2016)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      This work presents an experimental demonstration of a scheme based on an internally modulated fiber ring laser for high-sensitivity temperature sensing. The attained temperature resolution has been as low as ± 2pm even ...
    • Programmable retiming of an optical clock signal using the temporal Talbot effect 

      Tainta Ausejo, Santiago Upna; Erro Betrán, María José Upna; Garde Alduncin, María José Upna; Muriel, M. A. (IEEE, 2019)   Artículo / Artikulua
      By using a Fourier processor based on the temporal Talbot effect and the properties of the Discrete Fourier Transform, we propose a scheme that adds an adjustable delay to a train of pulses while simultaneously preserving ...
