Nonlinear-optic (NLO) compositions containing functionalized merocyanine dyes, such that the molecules, comprising the NLO-active compositions have a functional group at each end of the molecule and each functional group differing in reactivity, thus permitting stepwise reaction of each functional group, and NLO-active molecules prepared from hemioxonol dyes derviatived with (meth)acrylate or (meth)acrylamide groups, and their uses in devices such as second harmonic generators or polymer integrated optics.

Nonlineaphores and polymers incorporating such nonlineaphores

Devices for and method of generating coherent second harmonic light radiation. The devices comprise a laser source of coherent light radiation at a fixed fundamental frequency, crystalline 5-chloro-2-nitroaniline that crystallizes in a non-centrosymmetric configuration, means for directing the output radiation of the laser onto the 5-chloro-2-nitroanilane, and output means for utilizing the second harmonic frequency.
