The electrooptical properties of Ultradel{reg_sign} 9000D polyimides doped with dyes DCM and DADC, a bis(carbazole) analog of DCM with improved thermal stability, are reported. Cure temperatures were restricted to 240C or less to minimize potential thermal degradation of these dyes. Low poling fields of 30 V/{mu}m were used in these experiments and yielded r{sub 13} coefficients in the 0.1--0.8 pm/V range. Photothermal deflection measurements of dye-doped Ultradel 9000D samples showed low optical absorption losses in systems cured at 175C, but losses exceeded 20 dB/cm in samples cured at 300C.
