Abstract

We report the development and characterization of a new photorefractive multifunctional ormosil consisting of a second-order nonlinear optical chromophore and a charge transporting group covalently bound to a silicon atom. The sol-gel technique is used to process this ormosil into a homogeneous, single-phase material which exhibits electrooptic and charge transporting properties. When doped with a photocharge generation sensitizer, the material shows photorefractivity as evidenced by the electric field dependence of the four-wave mixing diffraction efficiency and that of the two-beam coupling gain.

17. The rationale in performing experiments in this manner was to obtain electrooptic data that would be close for both thick and thin films. A non-centrosymmetric order and, thus, second-order optical nonlinearity induced by the electric field poling in 100 μm or more thick films can be quite different from that obtained in thin films because of difficulties in applying external fields of the same magnitude. As an example, 1 μm thick film can easily be poled at fields as high as 100 V/μm or 1 MV/cm; to obtain the same field across a 100 μm thick field would require application of a 10 kV DC bias.Google Scholar
