Abstract :
Summary form only given. Four examples of nonlinear optical effects are briefly described. The first of these is the presence of both the Pockels effect and optical activity in Bi12SiO20. As a second example, a polyisocyanate random copolymer containing an asymmetric chiral center and Disperse-Red-1 nonlinear optical chromophores is synthesized. Next, the induced chirality of a nonlinear optical chromophore and the chiral chitosan polymer complex is investigated for a potential candidate as a second order NLO material. Finally, a bent-shaped liquid crystal is introduced to study the electro-gyration effect
