摘要
利用机械线加工技术设计矩形压力槽制作了周期为600μm,周期数为60的长周期光纤光栅.实验研究了所制作长周期光纤光栅的温度和压力特性,并通过调整光纤和压力槽之间的角度改变长周期光纤光栅的谐振波长.采用此技术制作的长周期光纤光栅最大谐振峰值可达15dB,通过调整光纤与压力槽之间的角度可使谐振波长变化超过12nm.
Long period fiber gratings were mechanically fabricated through periodic rectangular pressure grooves method. The rectangular periodic pressure grooves were made by mechanical line processing technology with the groove period of 600μm and 60 grating periods. The pressure and temperature characteristics of the fabricated LPFG were studied with different pressure and temperature, respectively. The resonant wavelength could be adjusted by tilting the angle between the fiber and the grooved plate. The fabricated LPFG＇s maximum resonant peak is up to 15 dB and the range of tunable resonance wavelength exceeds 12nm by adjusting the angle between fiber and grooved plate.
