Second order nonlinear optical properties of poled polymeric thin Films

Karakus, Yusuf (1993) Second order nonlinear optical properties of poled polymeric thin Films. Doctoral thesis, Durham University.



In this thesis the electrical poling and second order non-linear optical, NLO properties of guest-host, side-chain and main-chain polymers are studied. In bisphenol-A polycarbonate, BPA-PC guest-host systems an enhancement in both the thermal stability and linear electro-optic coefficient can be observed. This can occur in guest- host systems where hydrogen bonding can arise. One example is DAN/BPA-PC guest- host polymer. In side-chain materials a commercially available polymer P-4VP can be poled. This material shows moderate electro-optic response following poling. A novel main-chain type material, where the NLO group is rigidly bonded to the main-chain in a 'V shape is studied for its poling and second-order NLO properties. The rigidity of the polymer is so high that only chain-end groups contribute to the response.
