摘要
介绍了晶体折射型梳状滤波器的工作原理,根据导出的滤波器传输特性表达式,深入分析了滤波器通带宽 度、通带中心波长、阻带特性等参数与构成滤波器的晶片厚度、各晶片光轴之间夹角的关系,得出的结论对设计和 加工此类滤波器具有指导意义。
The principle of comb filter based on crystal birefringence is introduced. From the expression of filtering transfer function deduced by Jones matrix, the relationship between the characteristics of comb filter and the parameters of crystal plates are analyzed in detail. The conclusions derived from the simulations are useful for designing and fabricating this type of comb filters.
