Abstract:
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.
