Abstract :
We propose a novel scheme to realize unicast and multicast in WDM-PON. Unicast data and multicast data are modulated in DPSK format and ASK format respectively. Reflective semiconductor optical amplifier is used to selectively erase the ASK signal by adjusting the injected optical power, and multicast is realized.
