【摘要】 非局域空间孤子的演化过程由非局域非线性薛定谔方程描述,一般情况下很难得到其相互作用过程的精确解析解,而只能退而求其近似解(比如通过变分法或者数值解)。但是,由于强非局域非线性介质的独特性质,强非局域空间光孤子由线性模型描述,其相互作用过程的求解变得相对简单。利用线性叠加原理,可以巧妙地构造出强非局域介质中双光束相互作用问题的精确解析解。指出了利用强非局域空间光孤子的相互作用特性实现全光开关的潜在可能性。更多还原

【Abstract】 The propagation of the optical beam in the nonlocal nonlinear media is modelled by the NNLSE.It is always difficult to get a analytical solution of the solitons interaction.Commonly One can only get a approximate solution,for example by variational method or numerical simulation.However,because of the peculiar characteristic of the strong nonlocal nonlinear media the strong nonlocal optical solitons are governed by a linear model,so it is easer to obtain the analytical solution of the solitons interaction by the linear superposition principle.Also we indicate the potential possibility to achieve all-optical switches making use of characteristic of the strong nonlocal solitons interaction.更多还原
