The polarization characteristics of high reflection gratings with shallow grooves and its application in the birefringent filters
摘要
用瑞利-傅里叶(Rayleigh-Fourier)数值方法及椭偏测量,研究了高反射正弦形浅光栅的偏振特性.当正向入射条件下,光栅周期与波长之比满足某一关系时,其反射光电场的两垂直方向分量相移差大的特性,制成了一种新颖的双折射滤光片,文中给出了这种双折射滤光片的初步实验结果.
Abstract
The polarization characteristics of high reflection gratings with shallow grooves are investigated by using Eayleigh-Fourier method and confirmed qualitatively by ellipsometric measurement. Due to its outstanding performance, i.e. a large phase shift of two perpendocular components of the electrical field under the normal incident condition. Preparation of a new type of birefringent filter is feasible and has realized. Its demonstrative experimental results are also given.
