Coherent and Incoherent Interactions between Discrete-Soliton Trains in Two-Dimensional Light-Induced Photonic Lattices

The coherent and incoherent interactions between discrete-soliton trains are numerically investigated in lightinduced two-dimensional photonic lattices. The solutions of discrete-soliton trains for diamond and square lattices are obtained by Petviashvili iteration method. It is found that for both the kinds of lattices, two in-phase （out- of-phase） discrete-soliton trains attract （repel） each other, and the intermediates are always accompanied with energy transfer. While the interaction forces between two incoherent discrete-soliton trains are always attractive.

在 discrete-soliton 火车之间的协调、支离破碎的相互作用数字地在导致光的二维的 photonic 格子被调查。去钻石和方形的格子的 discrete-soliton 火车的答案被 Petviashvili 重复方法获得。它为两个被发现那格子的类型，二同相(out-of-phase ) discrete-soliton 火车吸引(排斥) 对方，和中介总是伴有精力转移。当在二列支离破碎的 discrete-soliton 火车之间的相互作用力量总是是吸引人的时。
