      Projecte Final de Màster Oficial
      Accés obert
      [ANGLÈS] In this master thesis it has been designed a multimode interference device with great features, great bandwidth and strongly insensitive to hardware impairments. The device implements a 120º hybrid which may be ...

    • Disseny de dos circuits opto-electrònics desplaçadors de la longitud d'ona per xarxes d'accés per fibra òptica (FTTH) 

      Solé Sánchez, Víctor (Universitat Politècnica de Catalunya, 2012-11-21)
      Projecte/Treball Final de Carrera
      Accés obert
      [ANGLÈS] In this work it is presented the design and simulation of two different opto-electronic circuits to perform a wavelength shifting at optical network units (ONU) of Fiber To The Home (FTTH) networks. This significantly ...

    • Experimental demonstration of long-distance space-division multiplexing transmission over few-mode and multi-core fibers 

      Mestre Adrover, Miquel Àngel (Universitat Politècnica de Catalunya, 2013-02-13)
      Projecte/Treball Final de Carrera
      Accés obert
      [ANGLÈS] After the extremely fast growth over last two decades, single-mode fibers capacity is reaching its recently revealed fundamental limit, imposed by a combination of Shannon's information theory and fiber nonlinearities. ...

    • Free space intra-datacenter interconnects based on 2D optical beam steering enabled by photonic integrated circuits 

      Chaintoutis, Charidimos; Shariati, Mohammad Behnam; Bogris, Adonis (2018-09-01)
      Article
      Accés obert
      Data centers are continuously growing in scale and can contain more than one million servers spreading across thousands of racks; requiring a large-scale switching network to provide broadband and reconfigurable interconnections ...

    • Real Time Control for Intelligent 6G Networks 

      González Pacheco, Pol (Universitat Politècnica de Catalunya, 2023-06-27)
      Projecte Final de Màster Oficial
      Accés obert
      The benefits of telemetry for optical networking have been shown in the literature, and several telemetry architectures have been defined. In general, telemetry data is collected from observation points in the devices and ...

    • Single sideband techniques for next generation low-cost UD-WDM coherent PONs 

      Masanas Jiménez, Miquel (Universitat Politècnica de Catalunya, 2021-09-23)
      Projecte Final de Màster Oficial
      Accés restringit per acord de confidencialitat
      In this thesis, two applications for splitter-based, coherent passive optical networks (PONs) are investigated. Coherent technologies enable ultra-dense wavelength division multiplexing (UD-WDM), increasing the dedicated ...

    • Thermal characterization and stabilization of DFB lasers for access networks 

      Solé Vilajuliu, Roger (Universitat Politècnica de Catalunya, 2021-12-09)
      Projecte Final de Màster Oficial
      Accés obert
      Current optical communication schema are based on TDMA. New schema have been proposed that are based on WDM. A WDM based scheme needs all lasers to be stable at a fixed wavelength. The wavelength of a laser can be modified ...
