Abstract :
We propose a novel scheme to realize unicast and multicast in WDM-PON. Unicast data and multicast data are modulated in Amplitude Shift Keying (ASK) format and Differential Phase Shift Keying (DPSK) format respectively. Reflective Semiconductor Optical Amplifier (RSOA) is used to selectively erase the DPSK signal by controlling the optical switch, and multicast is realized.
