Paper Abstract

Polymers doped with nonlinear optical (NLO) chromophores are attractive candidates for manufacturing optical integrated devices, especially for applications based on second order non-linearities. Such optical devices require to select accurately the areas where the NLO push-pull molecules embedded in the matrix are oriented. This is usually achieved using patterned electrodes deposited onto the samples or microlithography techniques. We suggest a novel approach to control the spatial distribution of the oriented chromophores, based on the use of photopolymerizable mixtures. The formulation developed, which consists of a triacrylate monomer and a photoinitiator, is polymerized upon a visible light irradiation. It is doped with chromophores specially synthesized for this purpose, transparent at the actinic wavelength and highly soluble in the acrylate monomer. The doped photopolymerizable films are poled with a static electric field before irradiation and the orientation of the chromophores is then frozen in the desired areas by irradiating the samples with an appropriate pattern of light. We observed the ability of the polymerized medium to slow down the chromophore relaxation compared to the unexposed solutions. The influence of the formulation composition and irradiation parameters on the temporal stability of the chromophore orientation was studied through second harmonic generation measurements. Infrared spectroscopy measurements enabled to draw a correlation with the monomer conversion degree of the polymer host.
