本文研究了半导体掺杂复合材料微结构的各向异性对材料的光学非线性增强的影响。利用Stroud-Hui的表达式，我们给出了半导体掺杂复合材料的有效三阶光学非线性极化率的频率响应。结果表明，复合材料微结构的各向异性能够使得整体复合材料的非线性光学增强达1～2个量级。

The effect of anisotropic microstructure of semiconductor composites on the optical nonlinearity enhancement is investigated.The calculations are based on Stroud-Hui expression for effective third-order nonlinear susceptibility.The frequency dependences of effective nonlinear susceptibility for the anisotropic composites with semiconductor elliptic inclusions in an insulating host have been evaluated.The results indicate that the optical nonlinearity of bulk material may be enhanced by 1～2 orders of magnitude through anisotropic microstructure.
