By colliding two self-guided beams (solitons), we generate one, two, three, four, or possibly more stable solitons for a broad class of nonlinear material that spans threshold to power-law nonlinearities. This reproduction is shown to depend critically on beam stability, on the standard waveguide parameter V, and on a scaled angular beam separation theta/theta(c). The beams can also annihilate one another or create a stable beam from two unstable beams. Beam steering is possible by differentially changing soliton power or phase. Also, the colliding solitons induce versatile optical devices for the switching and steering of small-signal beams.
通过使两束自引导光束（孤子）碰撞，对于一大类跨越阈值到幂律非线性的非线性材料，我们能产生一个、两个、三个、四个或者可能更多的稳定孤子。结果表明，这种复制过程严重依赖于光束稳定性、标准波导参数V以及缩放后的角光束分离θ/θ(c)。光束之间也可能相互湮灭，或者由两束不稳定光束产生一束稳定光束。通过差分改变孤子功率或相位可以实现光束转向。此外，碰撞的孤子能诱导出用于小信号光束开关和转向的多功能光学器件。
