      Covenantee:   Danmarks tekniske universitet
      The present thesis has been devoted to the study of optical transmissions at 100 Gbps with coherently detected QPSK signals taking advantage of polarization multiplexing. Two di erent systems have been investigated: single ...
    • A Comparison of Nonlinear Media for All-Optical Signal Processing 

      Martínez Díaz, Jordi (Universitat Politècnica de Catalunya / Technical University of Denmark. Fotonik Department / Politecnico di Torino. Dipartimento di elettronica, 2013-07-31)
      Master thesis (pre-Bologna period)
      Open Access
      Covenantee:   Politecnico di Torino
      [ANGLÈS] This thesis is focused on benchmarking different nonlinear media that are currently used for all-optical signal processing. The materials survey has been based on both low linear losses and highly nonlinear ...
    • Mode Division Multiplexing using MIMO Processing 

      Porcar Pujol, Oriol (Universitat Politècnica de Catalunya / Technical University of Denmark. Department of Photonics Engineering - High Speed Optical Communications, 2012-02)
      Master thesis (pre-Bologna period)
      Open Access
      Covenantee:   Danmarks tekniske universitet
      [ANGLÈS] Mode division multiplexing technologies in multimode optical fibers are being considered as one of the possible solution to the ever growing user capacity demands. Problems derived from this kind of fibers can be ...
    • Modulation Format Conversion in Future Optical Networks 

      Cano Adalid, Javier (Universitat Politècnica de Catalunya, 2009-03)
      Master thesis (pre-Bologna period)
      Open Access
      The signal generation and receiver schemes of different modulation formats such as on off keying (OOK) in either non‐return to zero (NRZ) or return to zero (RZ), correlative coding and phase‐shift keying (PSK) are described ...
    • Optical regeneration in dual-pump fibre parametric amplifiers 

      Alegre Sesé, Òscar (Universitat Politècnica de Catalunya, 2013-04)
      Master thesis (pre-Bologna period)
      Open Access
      Covenantee:   Danmarks tekniske universitet
      [ANGLÈS] This thesis is about the fiber optical parametric amplifiers (OPA). These devices have attracted great interest due to their potential for applications in optical communication systems. The parametric amplification ...
    • Towards multi-terabit per second single wavelength links using multilevel modulation 

      Elbaile Elfau, Ana (Universitat Politècnica de Catalunya, 2009-01-13)
      Master thesis (pre-Bologna period)
      Open Access
      Orthogonal Time Division Multiplexing (OTDM) and advanced modulation formats represents the future in development of high speeds communications. In this text the feasibility of OTDM systems combining multilevel modulation ...
