Control of Cross-Sections and Optical Nonlinearity of Pt Nanowires and the Roughness Effect
Figure 10
The model of cancellation of the SHG signal from two types of asymmetric nanowires. The nonlinear polarizations induced by the incident electric field in direction 2 have opposite signs due to the asymmetric shapes. The reflected SHG lights should be cancelled by each other when the nanowires have random distribution.
