Abstract
We describe the production of Bragg gratings at 980 nm in two types of single mode polymer optical fibres. The first type is based on PMMA (polymethylmethacrylate) with a core of PMMA-PS copolymer with less than 5% PS (polystyrene). The second type is based on PMMA with the addition of PBzMA (polybenzylmethacrylate) and PEMA (polyethylmethacrylate) in the core. The success rate of inscribing gratings in the first and second type was 30 and 100%, respectively. The reflectivity varied from grating to grating. The disappearance of the gratings after a certain period of time is subject to further investigation.
