Abstract

We have demonstrated the surface plasmon-polariton interference using a long-range surface plasmon-polariton waveguide coupler. A clear interference fringe with the visibility of 87 % was observed. The coupling ratio of the waveguide coupler was estimated to be 64:36 by two-photon interference experiments.
