Analysis and Calculation of Optical Nonlinear Enhancement Factor of Metallic Nano-wire Array
金属纳米线阵列的光学非线性增强因子的分析和计算

The parallel infinite metallic cylinders are taken as the model of a nanowire array,a detailed theoretical analysis on the nonlinear optical enhancement of metallic nano-wire array through localized field enhancement and surface plasmon resonance has been presented in this paper, based on the mean-field approximation and the principles of nonlinear optics. The enhancement factors for parametric and non-parametric nonlinear optical effects of silver nano-wire array have been also calculated and discussed.
