A numerical treatment of the experimental data allows the retrieval of the transverse and longitudinal components of the modes propagating in a waveguide for Bloch surface waves.orthogonal componentsnear fieldBloch surface wavesNear-field polarization measurements based on two arbitrary, orthogonal optical field componentstext::conference output::conference paper not in proceedings
