Paper Abstract

We have studied the photorefractive properties of a composite consisting of the polymer PVK doped with 4,4'- pentylcyanobiphenyl and C60. The material is homogeneous, stable, and does not require a plasticizer agent. Net gain coefficients over 100 cm-1 are observed. Measurements of orientational and electro-optic responses indicate that the orientational response is large, but markedly inhibited. We also report dramatic gain enhancement in two-beam coupling and novel angle and electric field dependencies in this composite.
