    • Quaternary optical transmission system combining phase and polarization shift keying 

      Comellas Colomé, Jaume; Gené Bernaus, Joan M.; Prat Gomà, Josep Joan (2004-07)
      Article
      Accés obert
      A new optical transmission scheme which combines polarization-shift keying and differential phase-shift keying on the same optical carrier is proposed. Simulations carried out show a considerable tolerance toward different ...
    • Random number generation by coherent detection of quantum phase noise 

      Álvarez, Juan Rafael; Sarmiento Hernández, Samael; Lázaro Villa, José Antonio; Gené Bernaus, Joan M.; Pérez Torres, Juan (2020-02-17)
      Article
      Accés obert
      In 2010 Qi et al. [Opt. Lett. 35(3), 312 (2010)] demonstrated a random number generator based on the drift of the phase of a laser due to spontaneous emission, The out-of-the-lab implementation of this scheme presents two ...
    • Reducing the number of transceivers with probabilistic constellation shaping in flex-grid over MCF optical backbone networks 

      Perelló Muntan, Jordi; Gené Bernaus, Joan M.; Cho, Junho; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2023)
      Comunicació de congrés
      Accés obert
      This paper quantifies the potential reduction in the number of required transceivers that the use of probabilistic constellation shaping (PCS) can bring to Flex-Grid over multicore fiber (MCF) optical backbone networks, ...
    • Reduction of the tuning time of 1.5-µm three-section DBR lasers by controlling the transient currents 

      de Sousa, Ana Belén; Prat Gomà, Josep Joan; Gené Bernaus, Joan M. (2000)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      A dynamical simulation model for three-section DBR laser is extended to analyse the thermal effect under continuous tuning. A new method to compensate the thermal drifts is implemented, and we have simulated a nonintrusive ...
    • Results and achievements of the ALLIANCE Project: New network solutions for 5G and beyond 

      Careglio, Davide; Spadaro, Salvatore; Cabellos Aparicio, Alberto; Lázaro Villa, José Antonio; Barlet Ros, Pere; Gené Bernaus, Joan M.; Perelló Muntan, Jordi; Agraz Bujan, Fernando; Suárez-Varela Maciá, José Rafael; Pagès Raventós, Albert; Paillissé Vilanova, Jordi; Almasan Puscas, Felician Paul; Domingo Pascual, Jordi; Solé Pareta, Josep (Multidisciplinary Digital Publishing Institute, 2021-09-30)
      Article
      Accés obert
      Leaving the current 4th generation of mobile communications behind, 5G will represent a disruptive paradigm shift integrating 5G Radio Access Networks (RANs), ultra-high-capacity access/metro/core optical networks, and ...
    • SDN-enabled flexible optical node designs and transceivers for sustainable metroaccess networks convergence 

      Sarmiento Hernández, Samael; Montero Herrera, Rafael; Altabas, Jose Antonio; Izquierdo, David; Agraz Bujan, Fernando; Pagès Cruz, Albert; Perelló Muntan, Jordi; Gené Bernaus, Joan M.; Alonso Varela, Marc; Pascual, Álvaro; Garces, Ignacio; Spadaro, Salvatore; Lázaro Villa, José Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The Internet data traffic constant growth caused by the popularization of cloud services, mobile and social networks, is being stressed by the advent of 5G technologies. Hence, architectural changes are required at the ...
    • Square-root strategy: a novel method to linearize an optical communication system with electronic equalizers 

      Prat Gomà, Josep Joan; Napoli, Antonio; Gené Bernaus, Joan M.; Omella Cáncer, Mireia Esther; Poggiolini, P.; Curri, Vittorio (2005)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      We demonstrate a nonlinear function after the photodetector that linearizes dispersion-limited IM-DD systems, enhancing the performance of linear electronic equalization. Results showed a clear improvement in terms of ...
    • SUNSET: sustainable network infrastructure enabling the future digital society 

      Lázaro Villa, José Antonio; Spadaro, Salvatore; Perelló Muntan, Jordi; Gené Bernaus, Joan M.; Altabas, Jose Antonio; Pagès Cruz, Albert; Careglio, Davide; Barlet Ros, Pere; Cabellos Aparicio, Alberto; Solé Pareta, Josep (Institute of Electrical and Electronics Engineers (IEEE), 2016)

      Accés restringit per política de l'editorial
      The ICT eco-system is constantly growing in traffic demands, with emerging cloud services, mobile and social network technologies to be integrated in 5G networks. New architectural changes at the underlying networks are ...
    • Towards broadly optimum multi-core fiber designs 

      Gené Bernaus, Joan M.; Winzer, Peter J.; Chen, Haoshuo; Ryf, Roland; Hayashi, Tetsuya; Sasaki, Takashi (The Institution of Engineering and Technology (IET), 2019)
      Text en actes de congrés
      Accés obert
      We show that key multi-core fiber (MCF) design parameters depend only weakly on the application scenario, from data-center interconnects to submarine links, leading to transmission-distance-independent optimum MCF ...
