作者描述了在双包层光纤中形成的单根长周期光纤光栅（LPG）中产生的自干涉条纹，双包层光纤的一端涂有金属FDM。所提出的LPG装置的反射光谱中的温度引起的条纹移位被测量为0.055nm/摄氏度，具有0.9摄氏度的RMS偏差。期望诸如滤波器和精细温度传感器之类的器件的应用。
The authors describe self-interference fringes created in a single long-period fibre grating (LPG) formed in a double-cladding fibre, one end of which is coated witj a metal fdm. The temperature-induced fringe-shift in the reflection spectrum of the proposed LPG device was measured to be 0.055nm/degrees C with 0.9 degrees C RMS deviation. Applications of such devices as filters and fine temperature sensors are expected.
