Abstract

With the structure of biprism, polarization beam splitting in a Glan-Taylor polarizer was explored based on the birefringence and Goos-Hanchen shift. Due to the birefringence of the light in calcite crystal, the extraordinary light worked as the position calibration. As for the ordinary light, the propagated direction tilted noticeably due to the refraction as well as Goos-Hanchen effect at the prism-air interface of in the air gap. The Snell's law and stationary-phase approach were utilized for the calculation of the beam splitting between the two orthogonal polarization elements. By choosing appropriate incident angle and initial polarization, remarkable beam splitting was realized. With this configuration, the resolution with a magnitude of and was achieved for the response of the incident angle and polarization detection respectively.

摘要

基于双折射和古斯-汉欣位移，利用双棱镜结构对格兰-泰勒偏振器中的偏振光束分裂进行了研究。由于方解石晶体中光的双折射，非常光起到了位置校准的作用。对于寻常光，在气隙中的棱镜-空气界面处，由于折射以及古斯-汉欣效应，其传播方向明显倾斜。利用斯涅尔定律和稳相法计算了两个正交偏振元件之间的光束分裂。通过选择合适的入射角和初始偏振，实现了显著的光束分裂。采用这种配置，分别实现了入射角响应和偏振检测的分辨率为和量级。
