the present embodiment is provided for complete disclosure of the present invention to fully inform the scope of the present invention to those ordinarily skilled in the art in the following description same drawing reference numerals are used for the same elements even in different drawings and explanations of the same elements are omitted according to a first aspect of the present invention there is provided a self poled eo and nlo 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 eo and nlo polymer is obtained by a polymerization reaction between the diacid diester monomer containing largely isomer with one directionally oriented chromophore in 3 dimensional space and a diamine here the organic chromophore is chemically attached to a polymer main chain and naturally oriented in one direction through molecular design of the monomer when the polymer is synthesized such that a poling effect can be obtained without an additional poling process when an aromatic group is in a main chain of the eo and nlo polymer the configuration of the polymer main chain varies according to the location of chemical bonding between the organic chromophore and the aromatic group and accordingly a 3 dimensional spatial orientation of the organic chromophore is significantly changed in the eo film therefore the polymer is manufactured by polymerizing a diacid diester isomer with one directionally oriented chromophore in 3 dimensional.
