Observation of the Photorefractive Effect in a Polymer

Abstract

We report the observation of the photorefractive effect in an amorphous electro-optic material, the nonlinear polymer bisphenol A diglycidyl ether 4-nitro-1,2,phenylenediamine (bisA-NPDA) make photoconductive by doping with the hole transport agent diethylaminobenzaldehyde-diphenyl hydrazone (DEH). The gratings formed exhibit: dynamic writing and erasure, strong electric field dependence, polarization anisotropy, diffraction efficiencies up to 6 x 10 -5 in a 356 micron film, and large estimated photorefractive space-charge fields. Continuous realignment of the nonlinear molecules in the polymer permits external control of the grating readout independent of the space charge field formed.
