摘要
系统研究了非局域非线性介质中的矢量涡旋孤子对的传输特性。矢量涡旋孤子对包含两个分量,一个分量是只有单峰的基态亮孤子,另一个分量是携带角动量的涡旋分量。根据变分法,得到任意非局域度范围,矢量涡旋孤子对的解析解,并推导出耦合系统中每个分量的传输方程。
The propagation of composite soliton-vortex pairs is systematically investigated in nonlocal nonlinear media.The composite soliton-vortex pair contains the fundamental component with the shape of a bright soliton and the vortex component carrying angular momentum. Based on the variational principle,we obtain analytical solutions of such composite soliton-vortex pairs in an arbitrary nonlocal regime,where evolution equations governed by coupled systems of equations describing each field are derived.
