Generalized 4 × 4 matrix formalism for light propagation in anisotropic stratified media: study of surface phonon polaritons in polar dielectric heterostructures: erratum [J. Opt. Soc. Am. B 34, 2128 (2017)]

In our paper J. Opt. Soc. Am. B34, 2128 (2017)JOBPDE0740-322410.1364/JOSAB.34.002128 in Section 2.C, the calculation of the layer-dependent electric field distribution is only valid for media with permittivity tensors that are diagonal in the lab frame, i.e., non-birefringent media. This erratum corrects Section 2.C such that the electric field distribution in birefringent media is calculated correctly. Further, Eqs. (20) and (33)–(36) are corrected. The associated MATLAB implementation has been updated.
