Abstract

We describe a type of multilayer dielectric coating designed to enhance the intensity of evanescent waves. The coating consists of a stack of alternating high- and low-index quarter-wave layers followed by a final low-index layer whose thickness is chosen to optimize the evanescent-wave intensity. Indirect measurements of the film properties are in good agreement with theory.

摘要

我们描述了一种旨在增强倏逝波光强度而设计的多层介质涂层。该涂层由交替的高折射率和低折射率四分之一波长层的堆叠组成，随后是一个最终的低折射率层，其厚度经选择以优化倏逝波光强度。对薄膜特性的间接测量结果与理论高度吻合。
