A novel up-stream transmitter for wavelength division multiplexed-passive optical network (WDM-PON) using a self-seeded reflective semiconductor optical amplifier (RSOA) was proposed. The RSOA was self-seeded by an amplified spontaneous emission itself using a fibre Bragg grating without an additional optical source. The side mode suppression ratio of self-seeded output signal and the extinction ratio were ∼28 and 8.1dB, respectively. Required power for 10-9 BER at 622Mb/s was about -28dBm and the power penalty after 20km transmission was <2dB for 30nm range of wavelength.
