    Backscattering en microanillos de silicio 
    Ballesteros García, Guillem (Universitat Politècnica de València, 2013-03-04)
    [ES] En este trabajo presentamos un técnica experimental para caracterizar el backscattering en microanillos resonantes de silicio, junto con un modelo analítico capaz de reproducir los resultados experimentales. El modelo ...

    Characterizing and modeling backscattering in silicon microring resonators 
    Ballesteros García, Guillem; Matres Abril, Joaquín; Martí Sendra, Javier; Oton Nieto, Claudio José (Optical Society of America, 2011)
    We present an experimental technique to characterize back-scattering in silicon microring resonators, together with a simple analytical model that reproduces the experimental results. The model can extract all the key ...

    High nonlinear figure-of-merit amorphous silicon waveguides 
    Matres Abril, Joaquín; Ballesteros García, Guillem; Gautier, Pauline; Fedeli, J.M.; Martí Sendra, Javier; Oton Nieto, Claudio José (Optical Society of America: Open Access Journals, 2013-02-25)
    The nonlinear response of amorphous silicon waveguides is reported and compared to silicon-on-insulator (SOI) samples. The real part of the nonlinear coefficient gamma is measured by four-wave-mixing and the imaginary part ...

    Low TPA and free-carrier effects in silicon nanocrystal-based horizontal slot waveguides 
    Matres Abril, Joaquín; Lacava, C.; Ballesteros García, Guillem; Minzioni, P.; Cristiani, I.; Fedeli, J. M.; Martí Sendra, Javier; Oton Nieto, Claudio José (Optical Society of America, 2012)
    We present the characterization of the ultrafast nonlinear dynamics of a CMOS-compatible horizontal-slot waveguide with silicon nanocrystals. Results are compared to strip silicon waveguides, and modeled with nonlinear ...

    Optical phase characterization of photonic integrated devices 
    Matres Abril, Joaquín; Ballesteros García, Guillem; Mas Gómez, Sara María; Brimont, Antoine Christian Jacques; Sanchis Kilders, Pablo; Martí Sendra, Javier; Oton Nieto, Claudio José (Institute of Electrical and Electronics Engineers (IEEE), 2014-07)
    We propose a relatively simple experimental setup, capable of accurately characterizing the optical phase response of an integrated photonic circuit. The setup is based on a phase-noise reduction scheme using an external ...
