Rogue waves that appear occasionally in the ocean have attracted great attention.[1-14] These waves can reach amplitudes of two,three or more times higher than the average crest,appear from nowhere and disappear without a trace.[1-4] Theoretically,the behavior of rogue waves can be well described by the nonlinear Schr(o)dinger equation (NLSE).[5,6] Experimentally,this novel phenomenon has been observed in nonlinear fiber optics[7,8] and water wave tanks.[9] Nowadays,studies on rogue waves have been extended to a variety of complex systems,such as two-mode nonlinear fibers[10-12] and multi-component Bose-Einstein condensates (BECs).[13] In this case,the coupled equations may describe rogue waves with higher accuracy than the uncoupled NLSE due to the fact that more than one wave amplitude needs to be considered.Interestingly,more abundant types of rogue waves[10-14]have been demonstrated in coupled systems.
