説明
Here, we will propose poly (cyano phenylene sulfide) as novel host materials of nonlinear optical (NLO) polymers. Our experimental results proved that NLO chromophore-doped PCPS thin films deposited on the metal layers exhibited second order NLO susceptibilities just by annealing at the temperatures higher than a glass transition point even without conventional poling procedures. We determined the optimized annealing temperatures and the film thickness for the nonelectrical poling procedure. The nonelectrical poling procedure was applicable for the films as thick as a few μm. The second order nonlinear coefficient of was 0.5 pm/V for the PCPS doped with 10w% of 4-[Ethyl(2- hydroxyethyl)amino]-4'-nitroazobenzene. Taking advantage of the unique polarization self-organization procedure, we may prepare one- or two-dimensionally periodically poled structures in these materials for the second-order NLO active photonic crystals pretty easily.
