  • Optical nanoantennas as cavities : nanoscale control of couplings strength and single photon emission 

    Singh, Anshuman (Universitat Politècnica de Catalunya, 2017-11-11)
    Tesi
    Accés obert
    Optical nanoantennas confine light on the nanoscale, enabling strong light-matter interactions with potential for ultra-compact optical devices. Apart from the direct applications in optical nanoscopy and sensing, nanoantennas ...
  • Quantum light source compatible with solid-state quantum memories and telecom networks 

    Rieländer, Daniel (Universitat Politècnica de Catalunya, 2016-11-24)
    Tesi
    Accés obert
    This PhD thesis is in the scope of experimental quantum communication. It deals with correlated photon pairs of which one photon is stored in a solid state device, while the other photon is at telecom wavelength. Quantum ...
  • Unravelling 3D cargo transport dynamics at the microtubule network with super-resolution microscopy 

    Verdeny Vilanova, Ione (Universitat Politècnica de Catalunya, 2016-10-13)
    Tesi
    Accés obert
    Intracellular transport plays an essential role in a wide variety of fundamental cellular processes required to maintain the internal regulation and organization of cells. Different types of cargos such as organelles, ...
  • Copper indium sulfide colloidal quantum dot solar cells 

    So, David (Universitat Politècnica de Catalunya, 2016-10-19)
    Tesi
    Accés obert
    The ubiquity of solar energy conversion technology is an exciting target which we aspire for in this century. Colloidal quantum dot (CQD) solar cells are an attractive platform, being low-cost and allowing facile control ...
  • Weak value amplification : new insights and applications 

    Salazar Serrano, Luis José (Universitat Politècnica de Catalunya, 2016-10-13)
    Tesi
    Accés obert
    Weak Value Amplification (WVA) is a signal enhancement technique proposed in 1988 by Aharonov, Albert, and Vaidman that has been widely used to measure tiny changes that otherwise cannot be determined because of technical ...
  • Elliptically polarized light for depth resolved diffuse reflectance imaging in biological tissues 

    Sridhar, Susmita (Universitat Politècnica de Catalunya, 2016-10-05)
    Tesi
    Accés obert
    Realitzat a/amb:  Aix-Marseille Université
    Polarization gating imaging is a popular and widely used imaging technique in biomedical optics to sense tissues, deeper volumes, and also selectively probe sub-superficial volumes. Due to the "polarization memory" effect ...
  • Quantum metrology with high-density atomic vapors and squeezed states of light 

    Lucivero, Vito Giovanni (Universitat Politècnica de Catalunya, 2016-10-14)
    Tesi
    Accés obert
    Nowadays there is a considerable progress in optical magnetometry and spin noise spectroscopy, which use magnetically-sensitive atomic ensembles and optical read-out, approaching the limits set by quantum mechanics. In ...
  • Towards the generation of isolated attosecond pulses in the water window 

    Cousin, Seth Lucien (Universitat Politècnica de Catalunya, 2016-09-12)
    Tesi
    Accés obert
    Attosecond science investigates the realm of processes that happen in fleetingly short passages of time. One attosecond to one second, is what one second is to the age of the universe! Advances in lasers and specifically ...
  • Photodetectors based on low-dimensional materials and hybrid systems 

    Kuffer, Dominik (Universitat Politècnica de Catalunya, 2016-06-13)
    Tesi
    Accés obert
    In the last decade, two-dimensional (2D) materials have attracted attention both in the nascent field of flexible nanotechnology as well as in more conventional semiconductor technol-ogies. Within the rapidly expanding ...
  • Impact of imperfections on correlation-based quantum information protocols 

    Passaro, Elsa (Universitat Politècnica de Catalunya, 2016-05-30)
    Tesi
    Accés obert
    Quantum information science is a rapidly evolving field both from the theoretical and the experimental viewpoint, motivated by the fact that protocols exploiting quantum resources can perform tasks that are unfeasible in ...
