Correction to: Nature Photonics https://doi.org/10.1038/s41566-025-01694-1, published online 19 June 2023.

In the version of this article originally published, there was an error in the fourth paragraph of the “Hyperspectral nano-photoluminescence imaging” section, where in the text now reading “Each mode ℓ = 0,1,2 … in Fig. 2 is fully defined…,” ℓ = 0,1,2 … first appeared as “β ≈ 0.8.” The error has been corrected in the HTML and PDF versions of the article.
