在总结金属反射镜及多层介质反射镜的优缺点的基础上 ,按照一维光子晶体的设计思想 ,提出用λ/4膜系设计特定波长范围内的全偏振全角度反射镜的方法 ,给出了反射带中心波长、边缘波长及带宽的表达式 ,并对如何避免 Brewster窗作了定量分析。
Based on the advantages and disadvantages of metal mirrors and multilayer dielectric mirrors, a method of designing fully polarimetric full-angle mirrors in a specific wavelength range with λ / 4 film was proposed according to the design idea of one-dimensional photonic crystals. The expressions of the center wavelength, the edge wavelength and the bandwidth of the reflection band are given, and how to avoid the Brewster window is quantitatively analyzed.
