    Abstract

    Based on nonlinear Schr dinger equation, we research the light field properties, including the distribution and the stability, and dynamical behaviors of multi-polar lattice solitons, distributed on a single channel or across different channels in nonlinear media with optical lattices. These survey results indicate that there are two kinds of multi-polar solitons such as in-phase soliton and out-of-phase soliton in such systems. Significantly, multi-polar lattice soliton distributed on a single channel can only be out-of-phase, but an in-phase multi-polar lattice soliton is not allowed. Among three kinds of multi-polar lattice solitons, stability of in-phase multi-polar lattice soliton is the worst, and that of out-of-phase multi-polar lattice soliton distributed across different channels is the best. If optical lattice is removed, three kinds of multi-polar lattice solitons present different dynamical behaviors. After the optical lattice is removed, an in-phase multi-polar lattice soliton first splits into a corresponding number of light beams, and then they merge into one beam, or their energy is redistributed, or they collide periodically. Nevertheless, the out-of-phase multi-polar lattice soliton splits into several light beams, and then the beams repel each other, in which two side light beams transmit forwards along their respective straight trajectories, and the angle between any of their straight trajectories and its original direction of propagation is equal; especially, light beams, generated from the fission of out-of-phase multi-polar lattice soliton with a small propagation constant, may diffuse when the optical lattice is withdrawn. These results may have certain value to all-optical controlling techniques such as all-optical routing and all-optical switching.
