We report writing polymer optical fiber (POF) gratings in photosensitive POFs doped with benzildimethylketal (BDK) (BPOF in short) using a 355 nm laser for what we believe to be the first time. Both multimode and single-mode FBGs were fabricated with relatively low writing intensity. The enhanced photosensitivity of the doped POFs is also evident by the observation of obvious change in the UV-visible absorption.
我们首次报道了使用 355nm 激光在掺有苯亚甲基二甲基酮(BDK)的光敏聚合物光纤(POF)中写入聚合物光纤光栅(POF)(简称 BPOF)。使用相对较低的写入强度制作了多模和单模 FBG。通过观察紫外可见吸收的明显变化,也证明了掺杂 POF 的光灵敏度增强。
