title: Ultralow loss visible surface plasmon based waveguides formed in indium-tin-oxide coated Fe-doped LiNbO3slabs.
abstract: Visible reconfigurable waveguides were evidenced in a composite system formed with indium-tin-oxide (ITO) films coated on iron-doped lithium noibate (LN) slabs. 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.
