Abstract
The Langmuir-Blodgett (LB) film-forming properties of a number of novel azobenzene dye polymers are reported. The linear and second-order non-linear optical properties of the films have been studied using ellipsometry, visible spectroscopy and Pockels effect measurements. As monolayers, the effective electro-optic r-coefficients ranged from 1 to 8.7 pmV.-1 When one of the polymers was combined in an alternate layer film (230 layers in total), an r13-coefficient of 13 pm V-1 was achieved. This is one of the highest values reported for a 'thick' LB film.
