Paper Abstract

Distinct electroabsorption grating and photoisomerization grating as well as photorefractive grating were observed in the composite consisting of 1-n-butoxyl-2,5- dimethyl-4-(4'- nitrophenylazo)benzene: poly(N-vinylcarbazole):2,4,7- trinitro-9-fluorenone in a weight ratio of 44:55:1. Based on the quick translation technique of two-beam coupling experimental geometry, we measured the electroabsorption gratin to be 6-7 cm-1, and photoisomeric effect also brought an absorption grating of 2-3 cm-1. Photoisomeric effect caused index grating was separated from the others by analyzing the dynamic behavior of the gratings, and an amplitude between 1 X 10-4-2 X 10-4 was obtained.
