Abstract
A photorefractive composite consisting of the polymer poly(N-vinylcarb azole) (PVK) doped with 4,4'-n-pentylcyanobiphenyl (5CB) and C-60 is r eported. The material shows no sign of phase separation, is stable, an d does not require a plasticizer agent. Gain coefficients over 100 cm( -1) are observed. Measurements of orientational and electro-optic resp onses indicate that the orientational response is large, but markedly inhibited. (C) 1998 American Institute of Physics.
