Polymeric guest-host system for nonlinear optical fibres

In summary, preliminary experimental study on nonlinear organic polymer fibre is carried out by characterising material losses, refractive indices, and thermal and mechanical properties of several organic polymers and a highly nonlinear organic compound (P-carotene). The polymerisation or copolymerisation conditions have been investigated and low loss samples for either core or cladding have been fabricated. Further, we have fabricated uniform PMMA/PEMA fibre preforms doped with carotene. The work is being continued to investigate other high nonlinearity organic compounds and to fabricate nonlinear polymer fibres, upon the completion of a fibre drawing setup.<
