We report on the synthesis of high-temperature electro-optic polyimides and the design of the electro-optic modulators based on these materials. Recently developed electro-optic polyimide has a glass transition temperature of 461°C. It can be processed in a thin light-guiding film form a precursor at a temperature of 160°C. DIfferent novel designs of electro-optic modulators are being considered. A single-arm double-mode interferometer configuration is proposed for a thin-film transverse electro-optic waveguide modulator with low driving voltage. The driving voltage could be less than 5V that makes it compatible with conventional silicon-based electronics. We also consider miniature longitudinal modulators integrated with fiber optics in Fabry-Perot configuration. The advantage of the approach is the use of a small size area of the electro-optic film where high optical quality cna be easily achieved. The approach is being testd for polyimides as well as for single-crystal organic films wtih high electro-optic coefficients.
