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.
A self-poled electro-optic and nonlinear optical polymer represented by Formula I, wherein among three types of isomers in a diacid-diester monomer in which an organic chromophore is chemically attached to an aromatic dianhydride, the self-poled electro-optic and nonlinear optical polymer is prepared from a diacid-diester monomer containing largely isomer with one-directionally oriented chromophore in 3-dimensional space and a diamine
A method of manufacturing a self-poled electro-optic and nonlinear optical polymer, the method comprising the steps of:
A film manufactured from a self-poled electro-optic and nonlinear optical polymer, wherein among three types of isomers in a diacid-diester monomer in which an organic chromophore is chemically attached to an aromatic dianhydride, the self-poled electro-optic and nonlinear optical polymer is synthesized from a diacid-diester monomer with one-directionally oriented chromophore in 3-dimensional space and a diamine.
