Abstract
The Langmuir-Blodgett (LB) film-forming properties of a number of nove l azobenzene dye polymers are reported, The linear and second-order no n-linear optical properties of the films have been studied using ellip sometry, visible spectroscopy and Pockels effect measurements. As mono layers, the effective electro-optic r-coefficients ranged from 1 to 8. 7 pm V.(-1) When one of the polymers was combined in an alternate laye r film (230 layers in total), an r(13)-coefficient of 13 pm V-1 was ac hieved. This is one of the highest values reported for a 'thick' LB fi lm.
