Transparent optical multicast by multi-wavelength conversion has revealed a brand-new way for performing data multicast function directly in the optical domain without passing through any electronics. In this paper, several simultaneous multiple wavelength conversion approaches for transparent optical multicast are discussed. Technologies and methods for single-to-multiple-channel wavelength conversions are summarized and compared. The main focus is on four-wave-mixing (FWM) wavelength conversion technique, because it is suitable for high bitrates and offers strict transparency to any data modulation format. Cross-gain modulation (XGM) wavelength conversion has limitations in these respects. Experimental results of FWM and XGM for one-to-twochannel conversion are presented.
