Thin films of polyetherketone guest–host polymer doped with 3-(1, 1-dicyanothenyl)-1-phenyl-4, 5-dihydro-1H-pryazole were prepared. Linear electro-optic coefficients of poled-polymer films have been determined at λ=632.8 nm by use of a simple interferometric technique. Temporal and temperature stability of the poled-polymer film was measured by probing linear electro-optic activity and second-harmonic signal intensity, respectively. For the poled-polymer films the lower-order optical waveguide-transmission losses were measured at 632.8 nm. The measurements showed that the optical loss of the fundamental mode was less than 0.5 dB cm<sup>−1</sup> for transverse electric-field polarization.
