Correction to: Nature Communications https://doi.org/10.1038/s41467-018-07533-y, published online 30 November 2018.

The original version of the Article contained an error in Fig. 2 in which the TEM images in Fig. 2b and d were incorrect. The correct version of Fig. 2 is:

which replaces the previous incorrect version:

Additionally, the seventh sentence of the ‘Mechanism for the dissymmetry enhancement of SCL field’ section of the Methods originally incorrectly read ‘Since the relative light intensity ratio \(R = \frac{{I_2}}{{I_1}}\frac{{E_2^2}}{{E_1^2}}\), the dissymmetry factor near the nodes of SCL field can be expressed as ‘\(g_{{\mathrm{SCL}}} = g_{{\mathrm{CPL}}} \times \frac{{\left( {1 + \sqrt R } \right)}}{{\left( {1 - \sqrt R } \right)}}\).’ The correct version states ‘\(R = \frac{{I_2}}{{I_1}} = \frac{{E_2^2}}{{E_1^2}}\)’ instead of ‘\(R = \frac{{I_2}}{{I_1}}\frac{{E_2^2}}{{E_1^2}}\)’. This has been corrected in both the PDF and HTML versions of the Article.
