    • Coherent control of light propagation in integrated optical waveguides 

      Menchón Enrich, Ricard (Universitat Politècnica de Catalunya / Universitat Autònoma de Barcelona, 2009-09-09)
      Master thesis
      Open Access
      Coherent control and manipulation of light propagation in systems of three coupled rib optical waveguides is addressed. We show that by an appropriate variation of the distance among waveguides, it is possible to transfer ...

    • Dynamics of a Bose Einstein condensate in a ring potential 

      Pino Quintana, Hernán (Universitat Politècnica de Catalunya / Universitat Autònoma de Barcelona, 2012-09-04)
      Master thesis
      Open Access
      [ANGLÈS] We have addressed the dynamics of a repulsive interacting 87 Rb Bose Einstein condensate (BEC) in a ring potential trap. Our study has been focused in the analysis of the interference pattern that arises by the ...

    • Dynamics of matter wave solitons 

      Polo Gómez, Juan (Universitat Politècnica de Catalunya / Universitat Autònoma de Barcelona, 2012-09-04)
      Master thesis
      Open Access
      [ANGLÈS] We study the implementation of a matter wave bright soliton interferometer formed by a Gaussian potential barrier placed at the center of a harmonic trap potential. After numerically evaluating the transmission ...

    • Polymer optofluidic systems 

      Vila i Planas, Jordi (Universitat Politècnica de Catalunya / Universitat Autònoma de Barcelona, 2009-09-09)
      Master thesis
      Open Access

    • Transformation Optics in Coupled Waveguides 

      Kumar, Shubham (Universitat Politècnica de Catalunya / Universitat Autònoma de Barcelona, 2011-09-08)
      Master thesis
      Open Access
      English: The technique of transformation optics is applied to a system of three coupled waveguides undergoing adiabatic passage of a light beam. We show that it is possible, by applying different transformations to different ...

    • Velocity Filtering via Adiabatic Passage for subnanometer atom localization 

      Rubio López, Juan Luis (Universitat Politècnica de Catalunya / Universitat Autònoma de Barcelona, 2011-09-08)
      Master thesis
      Open Access
      English: A novel technique named Velocity Filtering via Adiabatic Passage (VFAP) is proposed and theoretically investigated to reduce the transverse velocity of an atomic beam. The role of the Doppler effect and the transfer ...
