    Open Access
    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 ...

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

    Overcome the limited modulation bandwidth of low cost uncooled To-can packaged RSOA (~400 MHz) and operate it at 3.125 Gb/s using homodyne techniques with the optimal performance for phase modulation via measured characteristics.
