A new multicasting scheme based on 1 to 8-wavelength conversion is proposed for future high-speed broadband networks. 40 Gbit/s optical time domain multiplexed (OTDM) data was used to simultaneously impose phase modulation on 4 CW channels, 3.6 nm apart. The resulting sidebands were filtered using an arrayed waveguide router (AWGR) to obtain 8 different 40 Gbit/s OTDM channels. The measured bit-error rates indicate a power penalty of less than 1.5 dB.
