- In spectrum-sliced wavelength-division-multiplexing (WDM) passive optical networks (PONs) based on injection-seeded reflective semiconductor optical amplifiers, the inevitable spectral filtering by multiplexer/demultiplexer leads to an increase in excess intensity noise (EIN). The increased EIN degrades the signal-to-noise ratio of the modulated optical signal. To reduce the EIN, we utilized flat-top passband arrayed waveguide gratings and a narrow-bandwidth seed light source in a WDM-PON. The feasibility of a 32 × 1.25-Gb/s WDM-PON with 100-GHz channel spacing over a 20-km single-mode fiber was successfully demonstrated with a negligible power penalty. © 2006 IEEE.
