Paper Abstract

Photorefractive polymers doped azo-dye with electric field poling and photoinduced poling whose wavelength is 633 nm using four-wave mixing and two-beam coupling experiment at 780 nm are investigated. An increase of diffraction efficiency by the effect of photoinduced poling through photoisomerization in photorefractive polymers is demonstrated. And the diffraction efficiency depends on the intensity of photoinduced poling beam, and it has peak value.
