Erratum: Thermo-optic soliton routing in nematic liquid crystals(Optics Letters (2018)43:10(2296-2299)` DOI: 10.1364/OL.43.002296)

We recently reported on controlling optical spatial solitons in nematic liquid crystals through changes of the sample temperature in Ref. [1]. In particular, we demonstrated that both trajectory and confinement of the self-induced waveguides can be altered by exploiting the thermo-optic dependence of the refractive indices and the mechanical constants. After publication, we have noticed misprints in the expression Eq. (3) detailing the walk-off dependence on the refractive indices of the material. The correct formula is (see, e.g., Ref. [2]) In addition, the vertical axes of the photographs in Figs. 1–4 were affected by a scaling error. Here, we provide revised versions of the figures with amended y-axes. Figures 1–4 replace Figs. 1–4 of the previous article in print Ref. [1], respectively. Please note that the captions of all figures are the same as in Ref. [1]. While we apologize for the regrettable oversights, we stress that the error affected only the picture scaling, whereas the graphs Figs. 2(d) and 4(d) did show the correct values. Thus, the indicated scaling changes do not influence either the interpretation of the reported phenomena or the scientific conclusions of the article.
