| Abstract: | We have measured optical second harmonic generation (SHG) intensity from three types of Pt nanowires with 7 nm widths of elliptical and boomerang cross-sectional shapes, and with 2 nm width elliptical cross-sectional shapes on the MgO faceted templates. From the SHG intensities, we calculated the absolute value of the nonlinear susceptibility χ^(2) integrated in the direction of the wire-layer thickness. The tentatively obtained bulk χ^(2)B of the wire layer was very large, approaching the value of the well-known nonlinear optical material BaTiO_3. |
