Theoretical studies suggest that particular classes of organic molecules possess promising features with respect to second order optically nonlinear effects (frequency doubling, Pockels effect, etc.). These attractive features allow the application of such organic materials in integrated optical and electro-optic devices for manipulation of optical beams in communication or optical processing systems. Different forms of organic media, such as single crystals, Langmuir-Blodgett films, polymers, etc., exist and will be discussed and compared in this paper. In the case of side chain polymers, estimates of the expected second order nonlinear susceptibilities (x(2)ijK) and electro-optical coefficients (rmn) will be made, based on simple theoretical models. Experimental results, obtained with such optically nonlinear polymers, will be presented and compared with the theoretical predictions. The role of liquid crystallinity, in relation to the achievement of optical nonlinearity, is discussed, applying the results of an extended Maier-Saupe model.
