Abstract

The photosensitivity of copolymer optical fibre preform is analysed in comparison with the doped one. The effects of write conditions such as pump power and pump time have been studied. Then, the preform is drawn into single mode polymer optical fibre with core refractive index of 1.499, and core-cladding refractive-index difference of 0.008. Long-period birefringence gratings with period of 120 um are fabricated in the fibre. The duty cycle is 50%, and the refractive index change in the exposed area is about 1 × 10-3.
