In this work we report on the preliminary results of compatibility, fabrication and characterization of two planar polymeric multilayer structures for electro-optic applications. The structures are composed by three polymeric layers grown on glass substrate. Buffer and cladding layers were synthesized using polymethylmethacrylate (PMMA). The guiding layers were composed by Polysulfone (PSU) and by a mixture of PMMA and polycarbonate (PC) both doped with Disperse Red 1 (DR1) molecules as nonlinear active units. Linear and nonlinear optical characterization of the structures by refractive index, absorption, optical losses, Second Harmonic Generation (SHG) and time stability measurements have been carried out.
Guest-host polymer system with potential use in electro-optic devices is discussed. The polymer host is a polyimide and the guest chromophore is Disperse Red 19 (DR 19). Decay times of poled order after corona poling procedure have been derived from the behaviour at elevated temperatures below glass transition temperature T<sub>g</sub> using Arrhenius plots. An extrapolated lifetime greater than 30 years at room temperature has been obtained.
