    • Coherent UD-WDM RoF Fronthaul network with D-EML transmitter and phase-noise robust receiver 

      Masanas Jiménez, Miquel; Tabares Giraldo, Jeison; Prat Gomà, Josep Joan (2021-12-01)
      Article
      Accés obert
      This work proposes and tests a simplified coherent uplink architecture for ultra-dense coherent analog mobile Fronthaul with phase noise cancellation based on single sideband modulation of a dual-EML. Results show optical ...

    • Demonstration of continuous multiple access with homodyne and image-rejection heterodyne coherent receivers using directly modulated laser transmitters 

      Masanas Jiménez, Miquel; Tabares Giraldo, Jeison; Cano Valadez, Iván Nicolás; Prat Gomà, Josep Joan (Institute of Electrical and Electronics Engineers (IEEE), 2023-07)
      Article
      Accés obert
      This work presents a comprehensive set of experiments for the multipoint-to-point coherent passive optical network (PON), where the wavelength locking between the optical network unit (ONU) and optical line termination ...

    • Demonstration of continuous multiple access with image-rejection coherent receiver and DML transmitters 

      Tabares Giraldo, Jeison; Masanas Jiménez, Miquel; Cano Valadéz, Iván Nicolás; Prat Gomà, Josep Joan (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      We demonstrate a UD-WDM PON using DML transmitters with multilevel intensity modulation, both in base-band and RF, and a spectrally-efficient heterodyne receiver. We provide comparison with a homodyne receiver. Two users ...

    • Rayleigh backscattering rejection in single-laser homodyne transceiver for UD-WDM using λ-Shifting 

      Masanas Jiménez, Miquel; Santos Blanco, M. Concepción; Tabares Giraldo, Jeison; Polo Querol, Víctor; Prat Gomà, Josep Joan (2021-04-01)
      Article
      Accés obert
      With the aim of using a single laser per transceiver in single fiber splitter-based passive optical networks (PON) with coherent homodyne receivers, we apply wavelength shifting in an ultra-dense wavelength division ...

    • Simple single-laser coherent transceiver based on low-cost D-EML for edge networks 

      Masanas Jiménez, Miquel; Polo Querol, Víctor; Prat Gomà, Josep Joan (Institute of Electrical and Electronics Engineers (IEEE), 2023-03-15)
      Article
      Accés obert
      In this work we demonstrate single-laser, D-EML based coherent transceivers which transmit and simultaneously receive optical single sideband modulations through a phase noise cancelling scheme, leading to phase-noise 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 ...

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

      Masanas Jiménez, Miquel; Polo Querol, Víctor; Prat Gomà, Josep Joan (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Two applications for splitter-based, coherent passive optical networks are investigated. Coherent technologies enable ultra-dense wavelength division multiplexing, increasing the dedicated data rates per application, the ...

    • Wavelength shifting for ultra-dense homodyne coherent optical access networks 

      Masanas Jiménez, Miquel (Universitat Politècnica de Catalunya, 2020-07)
      Treball Final de Grau
      Accés obert
      In this work, a splitter based coherent passive optical network (PON) architecture for access over a single fibre is proposed. This PON enables ultra-dense wavelength division multiplexing (ud-WDM) while using a single ...
