Abstract :
An investigation has been conducted into dicyano compounds as second-order and phthalocyanine derivatives as third-order nonlinear optical materials. Ortho-methyoxy-benzalmalononitrile (DIVA) showed very large second order nonlinearity (d/sub eff/=4.9*10/sup -8/ esu at phase-matching condition) and had a good crystallinity which is very important for making optical devices. Phthalocyanine derivatives have fine processabilities for thin films and large third-order nonlinearity. Vanadyl phthalocyanine has especially large suspectibility ( chi /sup (3)/=3.5*10/sup -10/ esu). Using organic molecular-beam epitaxy, extremely smooth thin films of phthalocyanine derivatives have been obtained.<>
