【摘要】 本文研究了由理想线偏振片和单轴双折射晶体波片(光轴平行波片表面)组成的双折射滤光片倾斜放置时的二阶色散和三阶色散特性。利用琼斯矩阵推导出了双折射滤光片的群延迟表达式,计算了双折射滤光片的二阶、三阶色散曲线,分析了色散规律,给出了波片厚度、光线入射角和光轴旋转角的变化对二阶、三阶色散的影响,并就色散特性与GT干涉仪进行了比较。更多还原

【Abstract】 We present theoretical investigations of the second- and the third-order group delay dispersion caused by a tilted birefringent filter (TBF) that is composed of a tilted birefringent plate sandwiched between two linear polarizers. By using Jones matrix we deduced the expression for the group delay of a TBF and calculated the corresponding second- and the third-order dispersion. The influence of the parameters such as the thickness, the tilting angle and the rotation angle of the birefringent plate on dispersions are analyzed. Comparison between the dispersion characteristics of a Gires-Tournois interferometer (GTI) and those of TBF is also presented.更多还原
