摘　　要：当光纤光栅粘贴于非均匀衬底材料中时,其反射谱带宽变化复杂。理论分析了在线性应变场作用下光纤光栅反射谱带宽线性展宽的原理,并利用自行提出的开口环机构及相关机械装置、驱动电路和控制软件,研制出一种新颖的光纤光栅带宽可控调谐装置。该装置测量精度高,实际带宽值与预设值的误差为±0.04 nm,带宽精确可控,最大调谐带宽值达6 nm。另外,该装置重复性好,操作简便,可应用于光纤通信及光纤传感领域。When the fiber Bragg grating is glued in the non-uniform underlay, the bandwidth of the reflection spectrum will change complexly. In this paper, we analyze the principle of linearly broadening of the bandwidth when the fiber Bragg grating is embedded in the linear strain field. And we develop a device with controllably tuning bandwidth of fiber Bragg grating using the opening loop proposed by ourselves , the related mechanical setup, driving circuit and software. The controllable device is of high precision with the maximum error± 0.04 nm and the maximum tuning bandwidth of the apparatus is up to 6 nm. The device also is characterized by precision repetition and easy operation so that it can be used in the optical communication and optical sensing.
