Azoaromatic (Azo) polymers have attracted much attention as materials for nonlinear and optoelectronic applications. In this work, nonlinear properties of the concerned material are first characterized by m-lines spectroscopic method. Then, photoinduced phenomena reported in the literature are summarized and experimentally found out. Therefore, these photoinduced properties are used to design and manufacture an optically controlled integrated device based on light wave intensity dependence of refractive index.
