Surface plasmon polaritions (SPPs) excited at the ITO/LN interface were believed to be behind the observed light guiding, which is inherent with superlow loss for its sub-nanometer modified layer. The forward near-surface-normal scattering and accompanying reduction of the specular reflectivity in the front ITO/LN interface are consistent with SPP excitation.
