摘要
利用反射系数的递推表达式研究了弱吸收 1 /4波长 (QW )多层介质镜的反射特性 ,引入了一个具有普适性的权重因子来定量描述镜子中各层对反射时延、反射率下降的贡献。为了方便使用 ,用介质折射率表示出了权重因子 。
The recursion expression applicable to a quarter wave (QW) multi layer dielectric film stack with weak absorptions has been used to study the reflection characteristics of mirrors. A weighting factor has been introduced to quantify the contributions of each constituent layer to such mirror characteristics as the reflection delay,reflectivity reduction,etc. For convenience,the weighting factor has been expressed in terms of the refractive indices of the individual layers of the mirror,based on which the reflection delay and reflectivity reduction have been discussed thereafter.
