Abstract
A polyamic ester (PAE) film, which shows an electro-optic (EO) and nonlinear optical (NLO) properties without a poling process, is prepared. The chromophore in the film seems to be slightly oriented normally to the film surface (transverse magnetic field (TM) direction even though the polymer solution is spin-coated. This is due to the nano-configuration structure of PAE controlled by introducing a designed chemical structure into the monomeric repeating unit of PAE. Manufacturing the relating devices can be simplified by using the self-poled polymer film as a polymer waveguide. Additionally, the EO property of the film is thermodynamically stable.
