| 摘 要： | 通过非线性玻璃吸收光谱中非本征吸收区的透射率分析非线性玻璃的非线性系数。把非线性玻璃中光电场满足的Ｍａｘｗｅｌｌ方程变换为一个非线性自治一阶常微分方程组，数值求解得到非本征吸收区的透射率随非线性玻璃非线性系数的大而单调减小的数值关系，指出非本征吸收区的透射率的不同反映了非线性玻璃非线性系数的不同，这为分析比较不同尺寸的半导体量子点玻璃的非线性系数提供了一种方便实用的方法。

| Abstract: | The optical nonlinear coefficient of nonlinear glasses is studied by transmission coefficient in a nonabsorption region or when absorption can be ignored. Numerical relations between nonlinear coefficient and transmission coefficient are presented. As nonlinear coefficient increases, the transmission coefficient decreases. The results can be used to analyze the nonlinearity of glasses embedded with semiconductor quantum dots. |
