为了实现与温度无关的窄带光滤波器，研制了一种光程长度与温度无关的三维无热波导。光路长度的温度系数成功地降低到传统波导的-2%。
To realise a temperature independent narrowband optical filter, a three-dimensional athermal waveguide for which optical path length is independent of temperature is developed. The temperature coefficient of the optical path length is successfully decreased to -2% of that of a conventional waveguide.
