Abstract
Optically nonlinear device elements such as directional couplers, switches, frequency stabilizers, optical parametric devices and modulators use as an optically nonlinear element a cross-linked triazine polymer containing a covalently bonded optically nonlinear dye moiety. A specific cross-linked triazine with this dye moiety may be made by cyclotrimerizing a p-(N,N-bis(4'-cyanatobenzyl)amino)-p'-(2,2-dicyanovinyl)azobenzene monomer. During polycyclotrimmerization or cure, the element is subjected to a poling voltage which aligns the dipoles of the dye moiety to give a large useful nonlinear susceptibility.
