  • Ultrathin semiconductor superabsorbers from the visible to the near infrared 

    Molet Bachs, Pau (Universitat Politècnica de Catalunya, 2017-07-08)
    Master thesis
    Restricted access - author's decision
    The design of ultrathin semiconducting materials that achieve broadband absorption is a longsought-after goal of crucial importance for optoelectronic applications. To date, attempts to tackle this problem consisted ...
  • Exploring optical aberrations with two experimental techniques. Applications on Ophthalmic Optics 

    Marzoa Domínguez, Antonio (Universitat Politècnica de Catalunya, 2017)
    Master thesis
    Open Access
    This work focuses on the general description of two methods for wavefront analysis: wavefront measurement by means of Shack-Hartmann (SH) wavefront sensor and Point-Diffraction Interferometry (PDI); and its potential ...
  • Closed-loop control of magnetic fields for atomic physics experiments 

    Luan, Jie (Universitat Politècnica de Catalunya, 2017-09-08)
    Master thesis
    Open Access
    This project explores the control of magnetic fields through active feedback, ultimately bringing the magnetic field noise level below the required threshold, for one single axis. An absolute stability of less than 400 uG ...
  • Quantum Monte Carlo study of one-dimensional bosons with finite range interactions 

    Camí Núñez, Víctor (Universitat Politècnica de Catalunya, 2017-06-19)
    Master thesis
    Open Access
    We have studied how the ground state and the one-body density distribution of a one-dimensional system of bosons trapped by a harmonic oscillator potential depend on the repulsive interaction between the bosons. This study ...
  • Chiral Quantum Optics with three-level atoms 

    Garcia Ruspira, Jordi (Universitat Politècnica de Catalunya, 2017-07-19)
    Master thesis
    Open Access
    We study the dissipative dynamics of a three level atom in a cascade configuration driven by two independent lasers and coupled to a semi-infinite waveguide. The coupling to the waveguide is chiral, in the sense that each ...
  • Fast measurement of diffusing patterns and its parameterization 

    Turull Mallofré, Aina (Universitat Politècnica de Catalunya, 2016-09-08)
    Master thesis
    Open Access
    Covenantee:  Universitat de Barcelona / Universitat Autònoma de Barcelona / Institut de Ciències Fotòniques (ICFO)
    When light strikes on a diffuser surface a new energy redistribution is created. The diffusion patterns depends on the material of the diffuser and how light reach the diffuser. The aim of this project is to characterize ...
  • Narrowband photon pair source compatible with solid state quantum memories 

    Lago Rivera, Darío (Universitat Politècnica de Catalunya, 2016-09-08)
    Master thesis
    Open Access
    The generation of narrowband photon pairs compatible with solid state quantum memories is shown and analysed. This study is made in two different steps. In the beginning we implement a photon pair source with a periodically ...
  • An optofluidic router in a low-cost (PDMS) platform for rapid parallel sample analysis 

    Goyvaerts, Jeroen (Universitat Politècnica de Catalunya, 2016-09-09)
    Master thesis
    Open Access
    Optofluidic system for (bio)chemical applications are becoming more demanding in terms of num- ber of control points, number of light sources and readout equipment. So far, most of these sys- tems require several light ...
  • Camera alignment system for passive safety crash tests 

    Mensa Vendrell, Genís (Universitat Politècnica de Catalunya, 2016-07-19)
    Master thesis
    Restricted access - author's decision
    The use of digital high-speed cameras to acquire relevant information is a standard for all the laboratories and facilities working on passive safety crash tests. The recorded information from the cameras is used to develop ...
  • Study of femtosecond laser beam focusing in a direct-write system 

    Van Eeckhout Alsinet, Albert (Universitat Politècnica de Catalunya, 2016-07-22)
    Master thesis
    Open Access
    Direct-write techniques appear as a versatile option in rapid-prototyping applications because they can directly transfer a custom pattern from a digital file. Lasers are a distinguished tool which allow to perform non-contact ...
