  • SOA/REAM as Vector Modulator for QAM Upstream 

    Schrenk, Bernhard; Fàbrega Sánchez, Josep Maria; Kazmierski, Christophe; Lázaro Villa, José Antonio; Prat Gomà, Josep Joan (2011)
    Conference report
    Restricted access - publisher's policy
    Simultaneous encoding of information in the optical phase and amplitude for upstream transmission is demonstrated with an integrated SOA/REAM of small form factor. The crosstalk penalties between the QAM tributaries are ...
  • Wavelength conversion towards Rayleigh backscattering tolerant PONs via four-wave mixing in SOA-based ONUs 

    Schrenk, Bernhard; Lázaro Villa, José Antonio; Prat Gomà, Josep Joan (2010)
    Conference report
    Open Access
    Wavelength shifting in PONs with downstream signal remodulation is presented, allowing upstream transmission over trees with 25km feeder and 1:32 split with penalties <2dB, originally Rayleigh backscattering limited. ...
  • Wavelength-tuneable remote node for enhanced resilience and optimization of WDM access networks 

    Lázaro Villa, José Antonio; Bonada Bo, Francesc; Schrenk, Bernhard; Costa, Liliana; Teixeira, Marco Antonio; Chatzi, Sotiria; Klonidis, Dimitrios; Tomkos, Ioannis; Prat Gomà, Josep Joan (IEEE Press. Institute of Electrical and Electronics Engineers, 2011)
    Conference report
