Abstract

Organic materials have attracted remarkable interest recently as promising candidates for electro-optic (EO) devices because of their substantially low dispersion of EO coefficients compared to conventional inorganic EO materials such as LiNbO₃.^1,2 Organic materials with EO coefficients higher than r₃₃ of LiNbO₃ have been reported.^3,4 Recently a method of fabricating self- assemble superlattice (SAS) layers of polymer materials has been discussed.⁵ The SAS layers were intrinsically accentric, and second harmonic generation (SHG) and EO effects have been demonstrated without external electric field poling process.^6,7
