石英晶体旋光光学滤波器的特征参量

利用Müller矩阵和Stokes参量,从石英晶体旋光光学滤波器的透射比公式,推导出了石英品体旋光光学滤波器特征参量的理论计算公式.研究发现,特征参昼的值与滤波器的级数和滤波器中最薄石英晶体的厚度存在直接联系.计算得到一、二、三级石英晶体旋光光学滤波器在不同透射主峰的特征参量,并对其进行了实验验证.通过对不同透射主峰的特征参量进行比较可以看出,对于确定的滤波器,不同透射主峰处的自由光谱范围和通带半峰伞宽随着波长的增大而增大;同一透射主峰处的通带半峰伞宽随滤波器级数的增大而减小.

Characteristic Parameters of Quartz Optical Filter Based on Optical Rotatory Dispersion Effect

Using Müller matrix and Stokes parameter, theoretical calculation formulas for characteristic parameters of the quartz optical filter based on optical rotatory dispersion effect were deduced from the filter's transmission equation. The formulas show that the characteristic parameters have direct relationships with the stage number of the filter and the thinnest quartz's thickness. The filter characteristics of the one-, two-, and three-stage quartz optical filter at different main transmission peaks were calculated and proved by experiment. The filter characteristics were compared and the result shows that as the wavelength increases, the filter’s free spectral range and full width at half maximum at different peaks increase, and the full width at half maximum at the same peaks decreases with the filter's stage, number.
