基于相位掩模板的拉丝塔在线制作光纤布拉格光栅方法及装置研究
Study of Fiber Bragg Grating Fabrication Online on Draw Tower via Phase Mask Method and Equipment Manufacturing
摘要
拉丝塔在线制作光纤布拉格光栅(FBG)可以在单根光纤上制作无焊点串接的FBG阵列,有利于构建大规模的传感网络。尝试用相位掩模方法在拉丝塔上在线制作FBG,使用这种方法可以精确地控制所制作FBG的布拉格波长。针对相位掩模制作FBG的特点以及拉丝塔在线制作FBG的要求,研制了一套拉丝塔在线制作FBG的装置,使用此装置在拉丝塔上进行了实验,在线制作出由164个无焊点串接的FBG构成的FBG阵列。
Abstract
Fiber Bragg grating (FBG) fabrication on a draw tower can form a one-dimensional array of FBGs on a single fiber without welding spot between gratings, and is beneficial to build a massive sensor network. Phase mask method is employed to fabricate FBG online on a draw tower, by which we can precisely control the Bragg wavelength of FBG. A set of device is developed according to the characteristics of inscribing FBG by using phase mask method and the requirements of writing FBG on a draw tower. An array of 164 FBGs is produced on a single fiber by using this device.
