Plasmonic waveguides can transport light while still confining it beyond the diffraction limit. Recently, crossing plasmonic waveguides have been suggested for the implementation of higher-density optical networks. However, suppressing undesirable scattering at their crossing point is still a challenging task because waveguides in these structures are physically connected. Here, we present an experimental demonstration of surface plasmon propagation on an overcrossing metallic waveguide fabricated by a pick-and-place method. By spatially separating the waveguides, the undesirable interaction at the interconnection can be suppressed. Our approach could be a powerful platform to achieve high-density integration of optical waveguides.
