Abstract
The interaction between a metallic nanopartical(MNP) and dome semiconductor nanoshells hybrid system on the nonlinear optical properties has been discussed. By means of the effective mass approximation and the compact-density-matrix methods, we have studied the enhancement of surface plasmon resonances(SPRs) on the second-harmonic generation(SHG) and nonlinear optical rectification. The results reveal that SHG and optical rectification are affected obviously by the SPRs of MNP, and the influence is related to the inner and external radius of the spherical dome semiconductor nanoshells.
