摘　　要：给出了一种新型的制作长周期光纤光栅方法。在200℃高温下,利用高温金属胶将光纤粘贴到周期性波纹金属状结构上,当该器件降温到常温时,长周期光纤光栅形成。测试了该类光栅的温度特性,发现了光栅光谱谐振峰随温度调节而改变,并讨论了其机理。该器件可以用于实现可调谐滤波器和衰减器等器件。最后探讨了改变光纤直径易于成栅。A novel way to make long period fiber grating is proposed. Attaching fiber on a periodic ripple metal structure by high temperature metal glue at 200 ℃, a long period fiber grating is fabricated when the temperature of the combined structure declines to room temperature. The temperature characteristics of this kind of grating are tested, and the change of resonance peak for grating spectrum in different temperatures is discovered and its mechanism is discussed. This kind of grating can be used as optical fiber filter and optical fiber attenuator. At last, the easier grating realization by changing the diameter of optical fiber is also discussed.
