An apodized thickness design method for discrete layer notch filters is presented. The method produces error tolerant designs with low ripple in the passband regions without any additional numerical optimization. Several apodization functions including Gaussian, cosine squared, as well as quintic are considered. Theoretical and experimental results from ion beam deposited sample designs for single-notch as well as multinotch filters are presented. Good agreement is observed between the theoretical design and the experimental measurement even when the deposition process is only controlled on time. This demonstrates the low layer error sensitivity of the apodized designs.
提出了一种用于离散层陷波滤波器的变迹厚度设计方法。该方法无需任何额外的数值优化即可产生在通带区域具有低纹波的容错设计。考虑了几种变迹函数，包括高斯函数、余弦平方函数以及五次函数。给出了用于单陷波和多陷波滤波器的离子束沉积样品设计的理论和实验结果。即使仅通过时间控制沉积过程，理论设计与实验测量之间也观察到了良好的一致性。这证明了变迹设计对层误差的低敏感性。
