A downstream transmission using a wavelength-locked Fabry-Perot laser diode (FP-LD) with a spectrally sliced FP-LD as a WDM optical source is presented and experimentally demonstrated for application to a WDM passive optical network (PON) link. A side-mode suppression ratio (SMSR) of better than 40 dB is achieved by using an amplified and spectrally sliced FP-LD as an external-injection optical source. As a result, a downstream transmission of 622 Mb/s using a wavelength-locked FP-LD is successfully performed over 25 km. We can verify the feasibility of this method by its characteristics of simplicity, operational ease, and wavelength tunability.
