Matters Arising to this article was published on 30 April 2021

The Original Article was published on 27 April 2020

arising from: Hend Sroor et al. Nature Photonics https://doi.org/10.1038/s41566-020-0623-z (2020).

Metasurface-based orbital angular momentum (OAM) generation has attracted considerable attention recently1,2,3,4,5,6,7. The recently published article by Sroor et al. presents a very neat method for OAM optical state generation8. However, we suspect that the explanation of the operating principle provided by the authors is incorrect or incomplete. We anticipate that this could hamper future progress of metasurface lasers as well as of metasurfaces in general if left uncorrected.
