      Upgrading the capacity of backbone optical networks while delivering contents to the end-users with a reduced cost per bit is a day-by-day challenge of network operators. In this paper, we first discuss several mid-term ...
    • Simple intradyne PSK system for UDWDM-PON 

      Prat Gomà, Josep Joan; Polo Querol, Víctor; Zakynthinos, P.; Cano Valadéz, Iván Nicolás; Tabares, J.; Fàbrega Sánchez, Josep Maria; Klonidis, Dimitrios; Tomkos, Ioannis (2012-12-17)
      Article
      Accés obert
      A homodyne coherent receiver for ultra-dense WDM-PON with off the shelf components is presented. It consists of a conventional DFB, phase switched clock signal, an optical coupler instead of a 90º hybrid, balanced ...
    • Spectrally and spatially flexible optical networks: recent developments and findings 

      Shariati, Mohammad Behnam; Klonidis, Dimitrios; Marom, Dan M.; Comellas Colomé, Jaume; Velasco Esteban, Luis Domingo; Tomkos, Ioannis (Institute of Electrical and Electronics Engineers (IEEE), 2018-09-27)
