Holographic Recording on Azo-benzene Functionalized Polymer Film

- 論文の詳細を見る
Surface relief holograms are fabricated by irradiation of laser intensity pattern on the azo-benzene functionalized polymer films. The diffraction efficiency and the surface relief depth depend on the writing energy and the polarization of the laser beam. This structure is very stable at temperatures below the glass transition temperature $T_{\text{g}}$. The relief depth increases approximately ten times with the electric field by corona discharge at the temperature near $T_{\text{g}}$ even if there is no recording laser light. On the other hand, the surface relief disappears keeping the film temperature near $T_{\text{g}}$, neither recording laser beam nor external electric field. Using this material as a holographic memory, we demonstrate some memory modes, such as write-once, erase, rewritable, overwrite and data holding, under the combination of recording laser beam, external electric field and film temperature.
