We investigated optical second harmonic generation (SHG) from the arrays of V-shaped chromium nanoholes with the arm width of 50nm. We systematically investigated the dependence of the SHG intensity on the designed parameters of Cr nanoholes, i.e. the arm length and apex angle. Several combinations of structural parameters of apex angles (A) and arm lengths (L) were examined. The SHG intensity in Pin/Pout configuration was enhanced when L was enlarged. We suggest that the nonlinear optical behavior was dictated by the bulk contribution of metallic electrons.

Abstract

We investigated optical second harmonic generation (SHG) from the arrays of V-shaped chromium nanoholes with the arm width of 50nm. We systematically investigated the dependence of the SHG intensity on the designed parameters of Cr nanoholes, i.e. the arm length and apex angle. Several combinations of structural parameters of apex angles (A) and arm lengths (L) were examined. The SHG intensity in Pin/Pout configuration was enhanced when L was enlarged. We suggest that the nonlinear optical behavior was dictated by the bulk contribution of metallic electrons.
