      We report a new scheme to support, cost efficiently, ultra-dense wavelength division multiplexing (UDWDM) for optical access networks. As validating experiment, we apply phase modulation of a reflective semiconductor optical ...

    • Exploiting RSOA for uplink transmission with coherent detection for low cost UDWDM-PON 

      Chu, Guangyong; Lerín de la Santísima Trinidad, Adolfo; Cano Valadéz, Iván Nicolás; Polo Querol, Víctor; Tabares Giraldo, Jeison; Prat Gomà, Josep Joan (2014)

      Upstream phase modulation exploiting low cost reflective semiconductor optical amplifier (RSOA) at ONU is applied for simplified coherent detection through DFBs as local lasers at ONU and at OLT.

    • Monolithically integrated dual-output DEML for full duplex DPSK-ASK and DPSK-SSB ONU in ultra-dense channel spaced access network 

      Chu, Guangyong; Cano Valadéz, Iván Nicolás; Polo Querol, Víctor; Kazmierski, Christophe; Brenot, Romain; Prat Gomà, Josep Joan (Institute of Electrical and Electronics Engineers (IEEE), 2016-04)
      Article
      Accés obert
      Ultra-dense access network attracts people's attention recently; however, until now it is difficult to implement it commercially owing to cost, footprint, and the traditional complexity of coherent receiver. Single laser, ...

    • Optimizing reflective semiconductor optical amplifier as phase modulator for low cost colorless ONU with 3x3 homodyne detection 

      Chu, Guangyong; Polo Querol, Víctor; Lerín de la Santísima Trinidad, Adolfo; Cano Valadéz, Iván Nicolás; Prat Gomà, Josep Joan (2014)
