  • Surface and bulk harmonic generation in the opaque region of GaAs 

    Rodríguez Suñé, Laura (Universitat Politècnica de Catalunya, 2018-09-06)
    Projecte Final de Màster Oficial
    12 months embargo
    We demonstrate second and third harmonic generation from a GaAs substrate, far from the phase matching and well-below the absorption edge, in both transmission and reflection geometries. The pump is tuned in the transparency ...
  • Diffuse reflectance spectroscopy characterization of molecular absorption via graphene based photodetectors 

    Evans, Michael (Universitat Politècnica de Catalunya, 2018-09)
    Projecte Final de Màster Oficial
    60 months embargo
    This Master dissertation explores diffuse reflection spectroscopy as a viable tool for analytical chemistry, both quantitatively and qualitatively. In-vitro optical phantoms are created to mimic the turbid diffuse environments ...
  • 3D and multispectral imaging technology to aid in the diagnosis of skin cancer 

    Mancebo Prieto, Ana (Universitat Politècnica de Catalunya, 2018-09-06)
    Projecte Final de Màster Oficial
    Accés restringit per decisió de l'autor
    Skin cancer is one of the most frequent cancers in humans. The most important risk factor is UV radiation due to excessive sun. Melanoma is the most aggressive skin cancer and its incidence increases every year. Early ...
  • Towards cavity enhanced detection of single ions in the solid-state 

    Van Valkenhoef, Céline Hélène Ida (Universitat Politècnica de Catalunya, 2018-09-06)
    Projecte Final de Màster Oficial
    24 months embargo
    The goal of this master thesis was to take initial steps towards cavity-enhanced detection of single rare-earth ions in the solid state. A fibre microcavity set-up for use with Praseodymium-doped nanocrystals was designed, ...
  • Development of an image sensor platform for microorganisms in water 

    Sevilla Dalmau, Daniel (Universitat Politècnica de Catalunya, 2018-09-06)
    Projecte Final de Màster Oficial
    Accés restringit per acord de confidencialitat
    In this thesis, we demonstrate the correct operation of a fluorescence sensor designed for the analysis of water samples, in concrete phytoplankton levels and microorganism counting. The system, based on different techniques ...
  • Effect of stimulus unpredictability in time and magnitude on the vergence system 

    García Pérez, Javier (Universitat Politècnica de Catalunya, 2018-09-29)
    Projecte Final de Màster Oficial
    Accés restringit per decisió de l'autor
    Purpose: To study the influence of stimulus predictability (in magnitude and time) and subject?s expertise in vergence facility test in vergence latency times. Methods: Twenty-seven asymptomatic patients were evaluated ...
  • Solitons in non-linear ring micro-resonators 

    Benadouda Ivars, Salim (Universitat Politècnica de Catalunya, 2018-09-06)
    Projecte Final de Màster Oficial
    Accés obert
    We studied with the LugiatoLefever spatiotemporal formalism the existence, formation and dynamics of solitons in non-linear Kerr micro-resonators. For anomalous and normal dispersion we find different types of solitons, ...
  • Laser based transmitter for 5G networks 

    Scalabroni, Marco (Universitat Politècnica de Catalunya, 2018-09-06)
    Projecte Final de Màster Oficial
    Accés obert
    In our work, we searched a low-cost implementation of a laser-based transmitter for 5G communication. In particular, we designed a RF circuit for antenna communication and we explored the possibility of using a FPGA device ...
