Abstract

The design of single mode polymer optical fiber (POF) gratings was reported, combined by the Bragg condition, weakly guiding condition, single mode condition and the experimental conditions. In the following, the reflection spectrum of benzildimethylketal (BDK) doping POF gratings was simulated theoretically. Then photosensitive single mode POF doped with BDK was fabricated using Teflon technique, with the cladding of the copolymer of methyl methacrylate (MMA)-ethyl methacrylate (EMA) (60/40 v%) and the core of the copolymer of MMA-EMA-benzyl methacrylate (BzMA) (50/45/3 v%) doped with BDK (2 v%). At last, POF gratings were written in such a single mode photosensitive POF doped with BDK, whose Bragg wavelength is around 1572 nm, reflection intensity is about 7 dB, and the full width at half maximum is about 0.15 nm..
