摘要
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。
One dimensional photonic crystal omnidirectional reflector is a perfect mirror without the limits of metal mirror and multi layer dielectric mirror. In this paper, a kind of omnidirectional reflector in special spectrum band is introduced on the base of λ/4 film system. Formulas of the center wavelength and the edge wavelength of the reflection band are given. It is also analysed quantitatively that how the Brewster angle can be avoided in multiplayer designs.
