| Abstract: | The UV-Vis absorption of the azobenzene doped polymersample is measured and analyzed.In the nonresonant absorption,its photo-induced birefringence is studied.The relation of photo-induced birefringence signal and polarization angle is measured and the experimental result fits the theoretical curve well.Furthermore,it possesses large photo-induced birefringence signal and the characteristic of long-term optical storage.On this basis,the optical holographic storage was achieved by using molecular orientation. |
