| Abstract | We report a strong electroabsorptive effect in photorefractive composite of 1-n-butoxyl-2,5-dimethyl-4-(4??-nitrophenylazo)benzene: poly(N-vinylcarbazole): 2,4,7-trinitro-9-fluorenone with weight ratio 44:55:1. An electroabsorption coefficient of 27 cm-1 was measured at an applied field of 92.4 V/??m. The electroabsorptive effect depended strongly on the incident angle with respect to the direction of the applied field, which caused so-called orientationally enhanced electroabsorption grating in the composite. The electroabsorption grating was measured to be about 6 cm-1, 1/3 of which came from the variation of the value of the total electric field, and 2/3 caused by the variation of the direction of the total electric field. |
