Gratings fabrication in benzildimethylketal doped photosensitive polymer optical fibers using 355 nm nanosecond pulsed laser.
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.
