Abstract :
The polyetherketone (PEK-c) guest-host polymer planar waveguides doped with (4´-nitro)3-azo-9-ethyl-carbazole (NAEC) were prepared. The waveguide films were poled by corona-onset poling at elevated temperature (COPET), and the corona poling setup includes a grid voltage making the surface-charge distribution uniform. By using the prism-in coupling method, the dark-line spectrum given by the reflected intensity versus the angle of incidence have been obtained, and the optical transmission losses of mth modes have been measured for the poled polymer waveguides at lambda=632.8nm. The measurement result showed that the optical loss of the fundamental mode is less than 0.7 dBcm-1 for the TE polarization.
