Nature Communications 7: Article number: 12927 (2016); Published: 6 October 2016; Updated: 8 February 2018.

The original version of this Article contained an error in the caption to Fig. 2b, which incorrectly read ‘Localization length as a function of θ, the angle of incidence for λ=1 μm’. The correct version indicates that the calculation was performed for a wavelength of ‘λ=0.5 μm’ and not ‘λ=1 μm’. This has now been corrected in both the PDF and HTML versions of the article.
