论文摘要
我们对“用于拓扑涡流激光的自旋摩托锁的边缘模式”发表了评论，Phys。Rev.Lett。Vol。125，013903（2020）（2020）”（以下字母）。在字母中，Yang等人。报道了优雅的拓扑涡流激光器，并提出拓扑边缘模式激光的近场自旋和OAM具有一对一的远场辐射对应关系。近场信息基于拓扑边缘模式的频率分散，而无需支持测量和/或计算机模拟。不幸的是，它们在图1（c）中显示的频率分散体（另请参见补充材料中的图S6和等式（5.3）和（5.4））是错误的。结果，字母中研究的主模式| -2，+>的模式分配是错误的，应为| 2，+>。这破坏了信中声称的一对一信件。
We present a comment on "Spin-Momentum-Locked Edge Mode for Topological Vortex Lasing, Phys. Rev. Lett. vol. 125, 013903 (2020)"(hereafter the Letter).In the Letter, Yang et al. reported on an elegant topological vortex laser and proposed that the near-field spin and OAM of the topological edge mode lasing have a one-to-one far-field radiation correspondence. The near-field information is based on frequency dispersions of the topological edge modes, without supporting measurements and/or computer simulations. Unfortunately, their frequency dispersions shown in Fig. 1(c) (see also Fig. S6 and Eqs. (5.3) and (5.4) in Supplemental Material) are wrong. As the result, the mode assignment of the main mode |-2,+> investigated in the Letter is mistaken, which should be |2,+>. This spoils the one-to-one correspondence claimed in the Letter.
