Abstract :
The authors have investigated the polarization dependence of holographic gratings in chalcogenide Se/sub 75/Ge/sub 25/ thin film. They observed the vectoral effect, which depends on the polarization states. The high diffraction efficiency was induced by the photoinduced phenomena for the vertical polarization state and by wet etching with NaOH.
