研究了具有非局域聚焦非线性的介质中方位子，即旋转空间孤子的形成。我们证明了通过考虑经典的非旋转定常解的内模，即涡旋孤子，可以找到这些解的整族。这为在给定的非局域介质中识别方位子提供了一种详尽的方法。通过考虑可及孤子的强非局域极限，我们证明了不同涡度的方位子的形成，并解释了它们的性质。
We study the formation of azimuthons, i.e., rotating spatial solitons, in media with nonlocal focusing nonlinearity. We show that whole families of these solutions can be found by considering internal modes of classical non-rotating stationary solutions, namely vortex solitons. This offers an exhaustive method to identify azimuthons in a given nonlocal medium. We demonstrate formation of azimuthons of different vorticities and explain their properties by considering the strongly nonlocal limit of accessible solitons.
