Abstract: We have obtained the azimuthal angle dependence of the second harmonic (SH) intensity from bimetallic Pt/Cuand Pt/SiO/Cu nanowire arrays. The arrays were fabricated by shadow deposition on NaCl(110) faceted templates.The SH intensity from the Pt/Cu nanowire array measured in S_<in>/S_<out> polarization combination were 4.7 times larger than that from the Pt/SiO/Cu nanowire array at the fundamental photon energy of 2.33 eV. Phenomenologicalanalysis of the intensity patterns and numerical calculation of the local fields have shown that theinversion symmetry broken at the metal-metal interface is responsible for the enhanced SH generation from thePt/Cu bimetallic nanowire arrays.
