Research of new temperature-insensitive quartz filters

为了解决石英光滤波输出随温度敏感的问题,利用温度的变化对石英双折射率和旋光率具有相反变化趋势的原理,提出了一种由石英双折射滤波器和石英旋光滤波器组合而成的新型温度不敏感型的滤波器,采用数值分析和实验研究的方法研究了温度对该新型石英滤波器透射中心波长的影响。结果表明,该新型石英滤波器在一定温度范围内是不灵敏的。这为石英滤波波长温度不敏感的应用提供了一种自适应温度补偿的方法。

In order to solve the problem of being sensitive to temperature for output light of a quartz optical filter , based on the principle that the value of quartz birefringence and quartz rotation had opposite trend with the change of temperature , a new temperature insensitive quartz filter was presented combining a quartz birefringent filter with a quartz rotation filter .By numerical analysis and experimental methods , the impact of temperature on output center wavelength of the new type quartz filter was studied.The results show that new quartz filter is insensitive to temperature in a certain range .The new quartz filter provides adaptive temperature compensation for the insensitive temperature quartz filter .
