We investigate theoretically properties of partially coherent solitons in optical nonlinear media with slow saturable nonlinearity. We have found numerically that such a medium can support spatial solitons which are asymmetric in shape and are composed of only a finite number of modes associated with the self-induced waveguide. It is shown that these asymmetric spatial solitons can propagate many diffraction lengths without changes, but that collisions change their shape and may split them apart.
我们从理论上研究了具有慢饱和非线性的光学非线性介质中部分相干孤子的性质。我们通过数值计算发现,这种介质能够支持形状不对称且仅由与自感应波导相关的有限数量模式组成的空间孤子。结果表明,这些不对称空间孤子可以在不发生变化的情况下传播多个衍射长度,但碰撞会改变它们的形状并可能使其分裂。
