Abstract

The crosslinkable polymer matrices and NLO chromophores containing alkoxysilyl groups are used in this system to increase the stability of NLO property for sustaining photorefractive effect. The polymer systems with or without crosslinkable groups were prepared from PMMA, poly(MMA-co-TMSM), poly(VK-co-MMA) and poly(VK-co-TMSM) doped with modified DR1 (DRS) and modified carbazole (CzS). The photoconductivity and second harmonic generation measurements for poled thin films were carried out to manifest the photorefractive effect. The d₃₃ values were high (about 40 pm/V) and the temporal stability for crosslinkable polymer system was reasonably high (without UV-absorption change for 90 hrs). The electric field dependence of the photoconductivity was obtained by negative discharging method. Furthermore, photorefractivity was confirmed from two-beam coupling (2BC) measurements. It follows a value of the normalized gain coefficient Γ of 2∼13 cm^-1 at 633nm.
