Abstract

We analytically derive the general Dirac soliton solutions in a binary waveguide array with Kerr nonlinearity. These Dirac soliton solutions are more precise and more general than the simplified Dirac soliton solutions found earlier in binary waveguide arrays. The simplified Dirac soliton solutions can be straightforwardly obtained from the general Dirac soliton solutions under certain conditions. In this case, the profiles of both the general and simplified Dirac solitons are well maintained during propagation. In other cases, the general Dirac solitons better conserve their profiles during propagation than the simplified Dirac solitons.

二元波导阵列中一般狄拉克孤子解

本文解析导出了具有克尔非线性的二元波导阵列中的一般狄拉克孤子解。这些狄拉克孤子解比先前在二元波导阵列中发现的简化狄拉克孤子解更精确和更通用。在一定条件下，可以由一般狄拉克孤子解直接得到简化的狄拉克孤子解。在这种情况下，一般狄拉克孤子和简化狄拉克孤子的轮廓在传播过程中都得到了很好的保持。在其他情况下，一般狄拉克孤子在传播过程中比简化狄拉克孤子更好地保持其轮廓。
